makeWrapper: Remove unused extraFlagsArray feature
There is a bug in this feature: It allows extra arguments to leak in
from the environment. For example:

  $ export extraFlagsArray=date
  $ man ls

Note that you get the man page for date rather than for ls. This happens
because 'man' happens to use a wrapper (to add groff to its PATH).

An attempt to fix this was made in 5ae18574fc in PR #19328 for
issue #2537, but 1. That change didn't actually fix the problem because
it addressed makeWrapper's environment during the build process, not the
constructed wrapper script's environment after installation, and 2. That
change was apparently accidentally lost when merged with 7ff6eec5fd.

Rather than trying to fix the bug again, we remove the extraFlagsArray
feature, since it has never been used in the public repo in the ten
years it has been available.

wrapAclocal continues to use its own, separate flavor of extraFlagsArray
in a more limited context. The analogous bug there was fixed in
4d7d10da6b in 2011.

Orivej Desh 4199892768 makeWrapper: add --set-default and --set-eval
After #31497 starter quoting all values, there arouse the need to left some
values evaluated.

`--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`.

Nikolay Amiantov 29c0591dc1 makeWrapper: quote values properly
This uses Bash ${foo@Q} feature to quote values properly, which allows us to
handle values containing spaces, dollars etc.

Thanks orivej for the idea!

Taahir Ahmed e1d46c0c4d makeWrapper: Only wrap normal executable files
`makeWrapper` and `wrapProgram` are being invoked on all kinds of
wacky things (usually with the help of bash globs or other machine
assistance).

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.

Taahir Ahmed ece5387b09 makeWrapper: Die on unsupported arguments
Previously, makeWrapper would accept arguments it didn't recognize,
potentially allowing argument misspellings or broken callers.

Now, makeWrapper dies with a backtrace if it is called incorrectly.

Also changes `wrapProgram` so that it doesn't pass through the first
argument twice --- this was tripping up the argument checking.

Profpatsch 5ae18574fc stdenv/makeWrapper: make extraFlagsArray local
extraFlagsArray should not be exposed outside of `makeWrapper`, it
should only be possible to set it inside a script supplied via the
`--run` argument.

Vladimír Čunát 61b8d27b4c make-wrapper: fixup #14753 changes to make tests work
The tests need to expand passed variable and very carefully.
I could see no other easy way than to change single-quoting in
makeWrapper to double-quoting.
The tests now fail with the same problem as on master...

zimbatm 5e5494a852 make-wrapper.sh: add an --unset argument
`--set FOO ""` is not strictly equivalent to `--unset FOO`. In the former case
the environment variable still exists with an empty string as a value.

Thomas Tuegel 61cad61ebf makeWrapper: accept --argv0 flag (/cc #9562)
By default `makeWrapper` will not set argv[0] (this is a reversion to
the old default behavior). Based on the breakage we have seen from
changing the default, this is what most people want. The `wrapProgram`
function will send `--argv0 '"$0"'` to `makeWrapper`, i.e. it will
continue to pass-through the argv[0] that the wrapper is called with.

Eelco Dolstra 41840af689 * Add a setup hook ‘autoreconfHook’ to simplify packages that need to
run autoreconf:

    buildInputs = [ autoreconfHook ];

  is essentially equivalent to

    buildInputs = [ autoconf automake libtool ];
    preConfigure = "autoreconf -i";
