This is due to missing of include path in CFLAGS. That is, CFLAGS and GIT_VERSION macros are defined in the powerpc/ folder Makefile which in this case not involved.
To address the failure incase of executing specific sub-folder test directly, a new rule file has been addded by the patch called "include.mk" under selftest/powerpc/ folder and is linked to all Makefile of powerpc/pmu sub-folders.

Thanks for the fix Maddy. The patch fixes the reported problem for me.
