breakpointHook: add for debugging failing builds
Usuage: Add breakpointHook to your `buildInputs` like this:

  stdenv.mkDerivation rec {
    # ...
    buildInputs = [ breakpointHook ];
  });

When the build fails as show in this example:

  pkgs.hello.overrideAttrs (old: {
    buildInputs = [ breakpointHook ];
    postPatch = ''
      false
    '';
  });

It will halt execution printing the following message:

build failed in patchPhase with exit code 1
To attach to this build run the following command as root:

   cntr attach -t command cntr-/nix/store/ynyb4n82x2r7sldd58pbb405jdqh5f00-hello-2.10

Installing cntr and running the command will provide shell access to the
build sandbox of failed build:

sudo cntr attach -t command cntr-/nix/store/ynyb4n82x2r7sldd58pbb405jdqh5f00-hello-2.10
WARNING: bad ownership on /nix/var/nix/profiles/per-user/root, should be 1000
[nixbld@localhost:/var/lib/cntr]$

At /var/lib/cntr the sandbox filesystem is mounted. All commands and
files of the system are still accessible within the shell.
To execute commands from the sandbox use the `cntr exec` subcommand.

Revert "patch-shebangs: respect cross compilation"
This causes problems for packages built using a bootstrap stdenv,
resulting in references to /bin/sh or even bootstrap-tools. The darwin
stdenv is much stricter about what requisites/references are allowed but
using /bin/sh on linux is also undesirable.

eg. https://hydra.nixos.org/build/81754896

    $ nix-build -A xz
    $ head -n1 result-bin/bin/xzdiff
    #!/nix/store/yvc7kmw98kq547bnqn1afgyxm8mxdwhp-bootstrap-tools/bin/sh

autoPatchelfHook: Silence errors in isExecutable
The "maxx" package recursively runs isExecutable on a bunch of files and
since the change to use "readelf" instead of "file" a lot of errors like
this one are printed during build:

  readelf: Error: Not an ELF file - it has the wrong magic bytes at the
  start

While the isExecutable was never meant to be used outside of the
autoPatchelfHook, it's still a good idea to silence the errors because
whenever readelf fails, it clearly indicates that the file in question
is not a valid ELF file.

autoPatchelfHook: Only check PT_INTERP on execs
If the ELF file is not an executable, we do not get a PT_INTERP section,
because after all, it's a *shared* library.

So instead of checking for PT_INTERP (to avoid statically linked
executables) for all ELF files, we add another check to see if it's an
executable and *only* skip it when it is and there's no PT_INTERP.

Matthew Bauer f06942327a patch-shebangs: respect cross compilation
This hopefully makes patchShebangs respect cross compilation. It
introduces the concept of the HOST_PATH. Nothing is ever executed on
it but instead used as a way to get the proper path using ‘command
-v’. Needs more testing.

autoPatchelfHook: Run after patchelf's setup hook
So far the runtimeDependencies variable has been rather useless unless
you also set dontPatchelf, because the patchelf setup hook ran *after*
the autoPatchelfHook and thus stripped off the additional RPATHs added
using runtimeDependencies.

I did this by moving the autoPatchelfHook to be run in postFixup instead
of fixupOutput, however I needed to replicate the for loop that runs the
hook on all outputs.

Until we have a way to influence order of execution for hooks I've
marked this with an XXX so that we can use fixupOutput again.

Tested this against all packages that use autoPatchelfHook using the
following and checking whether the output contains any errors concerning
shared libraries:

nix-build -E 'with import ./. { config.allowUnfree = true; };
  runCommand "test-executables" {
    drvs = [
      masterpdfeditor franz zoom-us anydesk teamviewer maxx
      oracle-instantclient cups-kyodialog3 virtlyst powershell
    ];
  } "for i in $drvs; do for b in $i/bin/*; do \"$b\" || :; done; done"
'

pruneLibtoolFiles: init setup hook (#41819)
A .la file specifies linker flags to link with the library it describes. Its
"dependency_libs" field lists the libraries that this library depends upon.
This list often contains "-l" flags without corresponding "-L" flags. Many
packages in Nixpkgs deal with this in one of these ways:
- delete .la file [1]
- clear dependency_libs [2]
- add -L flags to dependency_libs [3]
- propagate dependencies [4]

Sometimes "dependency_libs" contain wrong "-L" flags pointing to the "dev"
output with headers rather than to the main output with libraries. They have to
be edited or deleted to reduce closure size [5].

Deleting .la files is often but not always safe [6].  Atomatically deleting as
many of them as possible is complex [7].  Deleting .la files that describe
shared rather than static libraries is probably safe; but clearing their
"dependency_libs" field achieves the same effect with less potential for
unintended consequences.  This is the approach that may be enabled for all
Nixpkgs.

autoPatchelfHook: Patch PIC exes/libs as well
If there is a shared object or executable that's using
position-independent code, the file's mime type is
"application/x-pie-executable", so until this change its dependencies
wouldn't be patched.

This simply adds the mime type to the search loop.

setup-hooks: Add autoPatchelfHook
I originally wrote this for packaging proprietary games in Vuizvui[1]
but I thought it would be generally useful as we have a fair amount of
proprietary software lurking around in nixpkgs, which are a bit tedious
to maintain, especially when the library dependencies change after an
update.

So this setup hook searches for all ELF executables and libraries in the
resulting output paths after install phase and uses patchelf to set the
RPATH and interpreter according to what dependencies are available
inside the builder.

For example consider something like this:

stdenv.mkDerivation {
  ...
  nativeBuildInputs = [ autoPatchelfHook ];
  buildInputs = [ mesa zlib ];
  ...
}

Whenever for example an executable requires mesa or zlib, the RPATH will
automatically be set to the lib dir of the corresponding dependency.

If the library dependency is required at runtime, an attribute called
runtimeDependencies can be used to list dependencies that are added to
all executables that are discovered unconditionally.

Beside this, it also makes initial packaging of proprietary software
easier, because one no longer has to manually figure out the
dependencies in the first place.

John Ericson da19c34d0f stdenv setup: Always use both propagated files
This continues #23374, which always kept around both attributes, by
always including both propagated files: `propgated-native-build-inputs`
and `propagated-build-inputs`. `nativePkgs` and `crossPkgs` are still
defined as before, however, so this change should only barely
observable.

This is an incremental step to fully keeping the dependencies separate
in all cases.

After #31497 starter quoting all values, there arouse the need to left some

`--set-default var value` expands to `export var=${var-value}`, where value is
not evaluated and literally assigned to var unless it is already set.

`--set-eval var value` expands to `export var=$(eval echo value)`, where value
is evaluated by `eval`.

`makeWrapper` and `wrapProgram` are being invoked on all kinds of
wacky things (usually with the help of bash globs or other machine

So far, I have come across `wrapProgram` being invoked on a directory,
as well as on the empty string.

As far as I can tell, it's only valid to invoke these utilities on a
normal (non-directory, non-device) executable file.  This commit
enforces that precondition.
