Agreed. Patches https://reviews.llvm.org/D51446 and https://reviews.llvm.org/D51312 apply fixes for the PPC64 toolchain. Similar fixes are needed for other architectures probably.
In general, it looks like this patch leads to some host macros having to be defined again for the auxiliary triple case. It is not clear to me how to exhaustively identify the missing macros, so far it's been just trial and error.
