Without the change tests like `xorg.imake.tests.pkg-config` fail as:
$ nix build --no-link -f. -L xorg.imake.tests.pkg-config

Let's always produce empty output for zero-modules tests.
The previous version didn't work in the case of relative symlinks in
subdirectories. If "foo/bar" was a link to "baz", it would check for
a link to "baz" in the root, rather than under "foo".
We don't need to dereference the symlink ourselves for [ anyway, as it
dereferences its arguments itself, so all we need to do to fix this is
to pass it the link.
Fixes: 14f83d5c6f ("compressFirmwareXz: fix links to directories")
The unwrapped version doesn't know where to look for libraries, so
this is required to e.g. build anything that uses openssl-sys with
OPENSSL_NO_VENDOR. A randomly chosen example package that's fixed by
this change is pkgsStatic.gitoxide.
We're already using pkgsBuildBuild, and we'll soon be using
pkgsBuildTarget, so for consistency, change buildPackages and
targetPackages to their corresponding two-component names.
Pass the whole environment to the native-image build process by
generating a -E option for every environment variable.
This has the same effect as setting
NATIVE_IMAGE_DEPRECATED_BUILDER_SANITATION=true
but is compatible with packages providing -E options themselves
Packages that require access to environment variables in the build
should specify these using `-E` arguments in `nativeImageBuildArgs` or
using a `native-image.properties` as described here:
https://www.graalvm.org/22.1/reference-manual/native-image/BuildConfiguration/#embedding-a-configuration-file
Specifying NATIVE_IMAGE_DEPRECATED_BUILDER_SANITATION=true breaks with
packages that list their environment variables explicitly in `native-image.properties`.
