I enabled -DCLANG_DEFAULT_PIE_ON_LINUX=OFF for clang-ppc64le-rhel: 
https://github.com/llvm/llvm-zorg/commit/b6ddf02ce3a54da2df29e7e599b1838167e0e3ad
which should fix the issues.

While I feel sorry for leaving clang-ppc64le-rhel red for some time and am 
willing to fix issues if I have access to a ppc64 machine (especially 
compiler-rt ones that I care about),
I feel uncomfortably if a group just bluntly request "please pull this patch" 
when apparently (a) there is a better approach (explicitly setting 
CLANG_DEFAULT_PIE_ON_LINUX=OFF) and (b) there is something a bot maintainer can 
do
and (c) there is just some inherent stability problem (in this case, consider 
not enabling the testing when the target is still unstable).
