I've used -fuse-ld=lld in a number of ports to unbreak -flto[2] or workaround /usr/bin/ld.bfd bugs[3] which weren't present in ld.bfd from devel/binutils. Other port maintainers do something similar. Can you show the build error from -fuse-ld=lld? [1] When a port defines USES=compiler:c11 (or similar due to -std=*) it uses lang/gcc10 on FreeBSD < 13 powerpc* which doesn't need -fuse-ld=lld because /usr/local/bin/ld is used by default. However, lang/gcc* with -flto will probably ignore -fuse-ld=lld due to IR/bytecode incompatibility and coincidentally avoid https://bugs.llvm.org/show_bug.cgi?id=47353 [2] Examples: multimedia/svt-*, graphics/mesa-devel [3] Examples: devel/basu, games/veloren, SVT* options in multimedia/ffmpeg
