Doing some more digging, the problem in the failing clang command seems to be the "--target=x86_64-unknown-linux-musl", which should be "--target=x86_64-gentoo-linux-musl".

[Comment 4 Felix Janda 2022-01-05 15:50:51 UTC]

clang++ --target=x86_64-unknown-linux-musl test.cpp for test.cpp containing only "#include_next <new>" reproduces the error (for both clang-13.0.0 and clang-12.0.1).

enable default_libcxx will workaround your issue at the moment, we have diagnosed this several times on #gentoo-hardened.

Enabling default-libcxx for sys-devel/clang allowed firefox to compile, thanks.
