When creating a profile containing both clang-toolchain and gcc-toolchain I see the same issue as in #43023; however, if I specify the default gcc-toolchain (currently gcc-toolchain@10) then clang and gcc work just fine together.

$ g++ hello.cpp && ./a.out
Hello World!

This is nice, but necessitates use of an old version of GCC until such time as core-updates is updated then eventually merged.
I'd like to instead use the latest gcc-toolchain (currently gcc-toolchain@11) and have clang-toolchain built with that gcc-toolchain. No matter what I offer in the "--with-c-toolchain" or "--with-input" options I always see the following error regarding '(assoc-ref %build-inputs "libc")' evaluating as false, even when specifying "--with-c-toolchain=clang=gcc-toolchain@10" that should currently be in use by default. Any ideas for fixing this?
Thanks,
Greg
