clang doesn't deal well with "-pie -static": it warns that -pie is an

clang, while keeping the gcc results identical.
The problem is visible when building via:
make LLVM=1 -C tools/testing/selftests
Again: gcc 13 produces identical binaries for all of these programs,
both before and after this commit (using "-pie"), and after (using
"-fPIE").
Also, the runtime results are the same for both clang and gcc builds.
Thanks for this! It got solved differently here:

Does that work for you as well?
