John Ericson b8a21aa918 misc setup-hooks: Use env vars to refer to binutils programs
This is more robust for cross-compilation

Guillaume Maudoux bfd522da63 setup-hooks: do not pass missing dirs to find (close #15405)
find fails when called with an inexistent search path.
That situation may arise when the output is created after by a postFixup hook.
vcunat amended the PR by clarifying one more `return` to `return 0`.

Eelco Dolstra d5bb6a1f9c glibc: Enable separate debug symbols
The importance of glibc makes it worthwhile to provide debug
symbols. However, this revealed an issue with separateDebugInfo: it
was indiscriminately adding --build-id to all ld invocations, while in
fact it should only do that for final links. Glibc also uses non-final
("relocatable") links, leading to subsequent failure to apply a build
ID ("Cannot create .note.gnu.build-id section, --build-id
ignored"). So now ld-wrapper.sh only passes --build-id for final
links.

Eelco Dolstra 2fcee55e5f separateDebugInfo: Create symlinks matching original binaries
For instance, a binary like libfoo.so will cause a symlink
lib/debug/libfoo.so.debug -> .build-id/<build-ID>.debug to be
created. This is primarily useful for use with eu-addr2line, if you
know the name of a binary and the relative address, but not the build
ID.

Vladimír Čunát b3658bc01b separateDebugInfo: compress it by default
Using zlib should be cheap enough and save lots of HDD space.
Case study (glib): 11 MB -> 4 MB.

Eelco Dolstra 2a28bc6691 separateDebugInfo: Assert Linux
Also remove some unintended setting of separateDebugInfo.

Eelco Dolstra ec5b66eb4a Enable separate debug info
You can now pass

  separateDebugInfo = true;

to mkDerivation. This causes debug info to be separated from ELF
binaries and stored in the "debug" output. The advantage is that it
enables installing lean binaries, while still having the ability to
make sense of core dumps, etc.
