Why are you using -fuse-ld=lld?

Because lld is significantly faster than the default.

But lld is not supported, you are on your own when using it (with GCC even more so).

gcc supplies and allows the -fuse-ld=lld argument, so I think in this case if it's present gcc should not emit incompatible flags for lld.

GCC does not know or probe what flags lld supports if it is not configured as the default linker. "not supported" was a statement for SUSE - lld is "supported" when used as the default linker as configured for clang/llvm, not when used with GCC. The "proper" fix would be to make lld recognize the flag if it claims to be compatible with BFD ld, or otherwise cease supporting -fuse-ld=lld.

I am aware that lld is not supported, but my time is also important and the difference in many builds, especially rust can be more than double by swapping to lld. For further, see https://github.com/rui314/mold#readme which has other comparisons.
