Comment (by bgamari):

 > LLD won't magically help here. Latest improvements by Martin Storsjö
 (mstorsjo) have made LLD able to link some mingw gcc-generated code, but,
 alas, when assembling GHC-generated assembly, mingw gas produces  (I
 believe this is a sort of "optimisation") non-standard relocations.

 Frankly I wonder how difficult it would be to add support for these
 relocations. Given that LLVM code is generally pretty approachable I
 suspect that would be the easiest path forward.

 In the meantime I have been pursuing testing Tamar's binutils patch.
