[cfe-dev] Compiler-rt fot ppc 32

[Nemanja Ivanovic via cfe-dev]

Hi Vikram,
I am sorry that I missed this email initially. It appears someone else also
has interest in enabling this build (https://reviews.llvm.org/D98831).

Of course, another possibility is to change the ppc_fp128 RTLIB calls for
32-bit PPC in PPCISelLowering.cpp.
