Run `deadnix . --edit`
`gccForLibs` is an argument used by multi.nix but it's an argument to
cc-wrapper, not to llvmPackages.
`@args` in `llvm/default.nix` was accidentally added in 4badff49fd
There are no uses of `@` therefore these changes are safe.
While using very old compilers is a fair usecase, it induces a maintenance churn as
we collect more and more LLVM versions for the LLVM maintainers.
Especially when we need to backport uniform changes to the whole tree,
furthermore, it consumes and waste CI resources.
CMake commit faa950a155 ("try_compile: Run native build tool with verbose output")
did not play well with these versions of openmp, which have a faulty
failure regex that considers "unknown" in the build output to indicate
a failure. When cross compiling, the string "unknown" is very likely
to occur as part of triples. Fix by backporting a patch that improves
the failure regex check to not be tripped up by triples.
The same problem affects LLVM 11 and possibly earlier, but the patch
doesn't apply that far back, so I didn't bother for now.

/nix/store/qwnvng0cbyx0bijm654jpmpl0516hfhx-libcxxabi-15.0.7-dev/include/cxxabi.h:20:10: fatal error: '__cxxabi_config.h' file not found
```
Before llvm 15 this used to work because `libcxx` copied the headers
from `cxxabi` to it's own `include`, which was then picked up by the
line above this one
Alternative fix would be to copy all files from `${cxxabi.dev}/include/c++/v1` to `${cxxabi.dev}/include` so the cc-wrapper setup hook would pick them up, but that would depend on in cxxabi being in buildInputs.
