Bug Description

== Justification ==
The selftests/powerpc/pmu/ebb test will fail on Ubunut PowerPC with:
   error while loading shared libraries: R_PPC64_ADDR16_HI reloc at
   0x00000f046fb04550 for symbol `' out of range

This is because the Ubuntu toolchain builds has PIE enabled by default.

== Fix ==
98415da0 (selftests/powerpc/pmu: Link ebb tests with -no-pie)

This fix will use -no-pie flag to build the test.

Patch already landed in Disco, and can be cherry-picked for B/C.
For Xenial, we don't have this test in our tree thus it can be ignored.

== Test ==
Patch verified on a Bionic P9 system, all the ebb tests will pass.

== Regression Potential ==
None.
This patchset is just for the kernel testing tool.

== Original Bug Report ==
