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
See docs.
Follow-up work:
- Existing packages should be converted
- `defaultPkgConfigPackages` should assert on `meta.pkgConfigModules`
and let `tests.pkg-config` alone test the build results.

platform.uname.processor seems to be what we want in many more cases
than what we were using before — it does the right thing for aarch64,
x86_64, riscv32, riscv64, mips, mips64, powerpc, and powerpc64 (the
latter three of which were broken before).
This fixes cross-compilation of systemd for PowerPC/POWER platforms.
Derivations listed as disallowedReferences or disallowedRequisites,
currently end up as build-time dependencies.
This is problematic since the disallowed derivations will be built by nix as
build-time dependencies, while those derivations might take a very long time
to build, or might not even build successfully on the platform used.
However, in order to scan for disallowed references in the final output,
knowing the out path is sufficient, and the out path can be calculated from
the derivation without needing to build it, saving time and resources.
While the problem is less severe for allowedReferences and allowedRequisites,
since we want the derivation to be built eventually, we would still like to
get the error early and without having to wait while nix builds a derivation
that might not be used (e.g. if we listed the wrong one).
A few potentially disruptive changes:
- binutils does not embed ${binutils-unwrapped}/lib as a default library
search path anymore. This will cause link failures for -lbfd -lopcodes
users that did not declare their dependency on those libraries. They
will need to add `libbfd` and `libopcodes` attributes to build inputs.
- `libbfd` and `libopcodes` attributes now just reference
`binutils-unwrapped.{dev,lib}` pair of attributes without patching
`binutils` build system.
We don't patch build system anymore and use multiple outputs out of
existing `binutils` build. That makes the result more maintainable: no
need to handle ever growing list of dependencied of `libbfd`. This time
new addition was `libsframe`.
To accomodate `out` / `lib` output split I had to remove `lib` -> `bin`
backreference by removing legacy lookup path for plugins.
I also did not enable `zstd` just yet as `nixpkgs` version of `zstd`
package pulls in `cmake` into bootstrap sequence.

FreeBSD doesn't use LLVM's cxxabi implementation, for backwards
compatibility reasons. Software expects the libcxxrt API when
building on FreeBSD. This fixes the build of
pkgsCross.x86_64-freebsd.boost.
Some other packages, for example ruby gems via buildRubyGem, use a
variable called "type" internally, which is overwritten here and
causes failures like:
failure: $gempkg path unspecified

`builtins.baseNameOf` retains any string context, causing the test
derivation to incorrectly depend on `pkgs.glibc`. All we really want is
to know what the dynamicLinker is called, but we don't need it to be
present in store.
Thanks to Adam Joseph for spotting this.
