Title:
powerpc/pmu/ebb test in ubuntu_kernel_selftest failed with "error
while loading shared libraries" on Bionic/Cosmic PowerPC

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.
