build log

The compilation fails with the clang toolchain, but i have the suspicion is the fault of lld,to be precise of the -fuse-ld=lld LDFLAG. Does binutils require another linker?

You have some interesting CFLAGS. Please try with a simple set of flags. If that resolves the issue, please try to figure out which flag(s) are triggering the failure.
Comment 5 Ionen Wolkens gentoo-dev 2021-06-06 12:16:17 UTC 
From the sound of it in other bugs, you're also using default-* on clang which tend to be further unexpected by packages.

Support for using clang globally (i.e. every packages) is already fairly limited, and along with these *FLAGS is likely to cause generalized failures. So I wouldn't call this an issue with these packages at the moment.

Please use more common toolchain settings.
