llvm/powerpc64*: fix broken binaries generated by clang12

Amends LLVM commit 2518433f861fcb877d0a7bdd9aec1aec1f77505a that
was pointed as the source of regression on LLVM12.

This affects powerpc64*, making binaries crash with segmentation fault
due to bad code generation around "__stack_chk_guard"

Root cause and/or proper fix is under investigation by:
