Revert "[compiler-rt][CMake] Enable TF intrinsics on powerpc32 Linux"

As mentioned in, this
change broke the build of compiler-rt targeting powerpc using GCC.
The 32-bit powerpc target is not supposed to emit 128-bit libcalls
-- if it does, then that's a backend bug and needs to be fixed there.

This reverts commit 8f24a56a3a9363f353c8da318d97491a6818781d.
