This commit adds a test of instruction counting using the PMU on powerpc.
Although the bulk of the code is architecture agnostic, the code needs to
run a precisely sized loop which is implemented in assembler.

This commit adds a powerpc subdirectory to tools/testing/selftests,
for tests that are powerpc specific.
On other architectures nothing is built. The makefile supports cross
compilation if the user sets ARCH and CROSS_COMPILE.
