What are the alternatives to GNU ld?

I was curious if it's possible to build Linux kernel without GNU toolchain (gcc+autotools). I found out that it is possible: after applying patches from llvm.linuxfoundation.org , it was possible to build Linux kernel with clang. GNU linker was used. The alternative to ld is gold which is also part of GNU binutils. Popular musl+clang toolchain ELLCC also uses GNU binutils. There are more alternatives: lld (no stable releases), mclinker (no stable releases). Does alternative to GNU binutils exist? Probably, building on Mac OS X or FreeBSD doesn't involve GNU tools.
