We should be very close.
I can't fully comment on ld but I actually had this bootstrapping with lld before the new year.
Then I was able to rebuild clang with that bootstrapped toolchain. (without exception handling)

There seems to be some regression with linking however since 4.0 which I will work through with pcc and rui soon.
I'm currently suspecting https://reviews.llvm.org/rL289776 is causing __imp_ prefixing that mingw doesn't like.
I think it is due to differences in how mingw handles dllimport vs msvc.
@compnerd would probably be the one to know the answer to this.
