This commit does the following two things:
1. Changes the Haskell package used in the extraDependencies test from
releaser to conduit. The reason for this is that conduit is more
of a "core" package in Haskell, and it is more likely to always be
working. (If conduit is not compiling, then large chunks of Hackage
won't be working.)
2. Tighten up the GHCi test to actually use the package from
extraDependencies. It appears that GHCi can fail to import the
package from extraDependencies, and that doesn't cause GHCi to
return an error code, which means the test isn't actually testing
anything.
This new change makes it so that if the package from
extraDependencies is actually not included for some reason, then
this shellFor test should fail.

This commit adds `pkgs.test.cross.sanity`, which is meant to be a
carefully curated list of builds/packages that tend to break when
refactoring our cross-compilation infrastructure.
It should strike a balance between being small enough to fit in
a single eval (i.e. not so large that hydra-eval-jobs is needed)
so we can ask @ofborg to check it, yet should have good examples
of things that often break. So, no buckshot `mapTestOnCross`
calls here.
Makes overrideAttrs usable in the same way that `override` can be used.
It allows the first argument of `overrideAttrs` to be either a function
or an attrset, instead of only a function:
hello.overrideAttrs (old: { postBuild = "echo hello"; })
hello.overrideAttrs { postBuild = "echo hello"; }
Previously only the first example was possible.

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
Some packages are only marked broken on specific platforms, so we
filter those out as well.
Consequently, this might not raise an error if the attribute value
needs to point to a different pkgs attribute, but this is not something
we can detect. For now, we'll have to rely on users of such pkg-config
packages to report that kind of error.
There's really not much we can do about this here.

This improves the error message
Error: _assignFirst found no valid variant!
which occurred when the set of outputs was not sufficient to set
the various outputDev, outputBin, etc variables. Specifically, this
would mean that "out" is not among the outputs, which is valid for
a derivation.
This changes the message to something like
error: _assignFirst: could not find a non-empty variable to assign to outputDev. The following variables were all unset or empty: dev out.
If you did not define an "out" output, make sure to define all the specific required outputs: define an output for one of the unset variables.
While this isn't a full explanation of what stdenv can and can not do,
I think it's vast improvement over the 0 bits of information that it
used to provide. This at least gives a clue as to what's going on, and
even suggests a fix, although probably multiple such fixes are required
in an instance where someone starts with a no-out derivation from scratch
(and decide to persist).
