--- Comment #15 from Fangrui Song <i at maskray dot me> ---
-- is definitely rare, but not non-existent.
In GCC, there is {-,--}specs.
In Clang, there are --cuda-path, --ptxas-path, --hip-path, --classpath, etc.

I do not see an objection to -fuse-ld=3Dword.

For --ld-path, -- is definitely rare, but not non-existent.
In GCC, there are {-,--}specs --sysroot.
In Clang, there are --cuda-path, --ptxas-path, --hip-path, --classpath, etc.

-fuse-ld=3D users mostly care about whether another linker can build their
programs, not whether the option can bootstrap GCC. I actually think ld.lld=
 is
quite sufficient in bootstrapping GCC but if there are edge-case extensions
which not supported, ld.lld developers may not want to the project with more
obscure options...
