selftests/powerpc/pmu: Link ebb tests with -no-pie

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

When running the ebb tests after building on a ppc64le Ubuntu machine:

$ pmu/ebb/reg_access_test: error while loading shared libraries:
R_PPC64_ADDR16_HI reloc at 0x000000013a965130 for symbol `' out of
range

This is because the Ubuntu toolchain builds has PIE enabled by default.
Change it to be always off instead.
