This change adds a flag to update shebang paths that point to the Nix
store. This is particularly useful when a cross-compiled package uses
same script at compile-time and run-time, but the interpreter must be
changed since hostPlatform != buildPlatform.
With a recent hackage update, turtle stopped compiling on ghc94. This
commit changes the tests.haskell.incremental test to use the temporary
package instead of turtle.
We shouldn't try compiling to aarch64-unknown-linux-gnu from
aarch64-unknown-linux-gnu, because that tends to confuse things and is
not representative of actual cross compilation usage.
This commit adds a derivation `gcc-stageCompare` to
`pkgs/test/stdenv/default.nix`.
It is important to always build this derivation whenever building
`stdenv`! Because we are using a Nix-driven bootstrap instead of
gcc's built-in `--enable-bootstrap`, the `gcc` derivation no longer
performs the post-self-compilation sanity check. You must build
this derivation in order to perform that sanity check.
The major benefit of this new approach is that the sanity check
(which involves a third compilation of gcc) can be performed
*concurrently* with all packages that depend on `stdenv`, rather
than serially. Since `stdenv` has very little derivation-level
parallelism it cannot take advantage of more than one or perhaps two
builders. If you have three or more builders this commit will
reduce the time-to-rebuild-stdenv by around 20% (one of three gcc
rebuilds is removed from the critical path, and stdenv's build time
is dominated by roughly 3*gcc + 1*binutils + 1*bison-test-suite).

Set the executable bit before running the check phase, so that the check
phase can run the script to test its behaviour.
This aligns with what `concatTextFile` is doing.
Also use explicit `if` statements so that we don't silently ignore
`chmod` failures.
with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
