[PATCH 1/3] perf tests: Add testing for Makefile.perf

[Jiri Olsa]

Currently we test only builds through top level Makefile,
but seems like there's a bunch of users using Makefile.perf
directly.

Changing the make suite to be run for Makefile.perf as well.
It takes now considerable amount of time, but hopefully we
catch more issues.

Also fixing the output indentation for make_kernelsrc and
make_kernelsrc_tools tests.
