Herald added a project: clang.

We can't (don't want to) honor the same set of "-fuse-ld" flags
with WebAssembly since the ELF linkers (ld.lld, ld.gnu, etc) don't
work with wasm object files.

Instead we implement our linker finding logic, similar or other
non-ELF platforms like MSVC.

We've had a few issues with CLANG_DEFAULT_LINKER overriding the
WebAssembly linker which doesn't make sense since there is no generic
linker that can handle WebAssembly today.
