On ELFv2 ABI Clang can't build this port by default and throws assertion (already reported):
Assertion failed: ((Op.getOpcode() == ISD::FP_TO_SINT || Subtarget.hasFPCVT()) && "i64 FP_TO_UINT is supported only with FPCVT"), function LowerFP_TO_INTForReuse, file /poudriere/jails/powerpc64-elfv2-pkubaj/usr/src/contrib/llvm-project/llvm/lib/Target/PowerPC/PPCISelLowering.cpp, line 7281.
