selftests: Add test of PMU instruction counting on powerpc 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.

selftests: Add install support for the powerpc tests The bulk of the selftests are actually below the powerpc sub directory. This adds support for installing them, when on a powerpc machine, or if ARCH and CROSS_COMPILE are set appropriately. This is a little more complicated because of the sub directory structure under powerpc, but much of the common logic in lib.mk is still used. The net effect of the patch is still a reduction in code.

selftests/powerpc: Don't ignore errors from sub Makefiles Currently we ignore errors from our sub Makefiles. We inherited that from the top-level selftests Makefile which aims to build and run as many tests as possible and damn the torpedoes. For the powerpc tests we'd instead like any errors to fail the build, so we can automatically catch build failures. We can achieve the best of both worlds by using -k, which tells make to keep building when it hits an error, but still reports the error.
