[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.

[PATCH 2/3] perf tests: Add test for make install with prefix

[Jiri Olsa]

Lukas Wunner reported issue (and fix) with 'make install prefix=...'.
Adding automated test for this, so it wouldn't happen again.

[PATCH 3/3] perf build: Fix single target build dependency check

[Jiri Olsa]

Currently if we build single target like:

  $ touch util/map.c && make util/map.o

It will not rebuild util/map.o if it already exists
and util/map.c is modified.

The reason is that the top-level 'Makefile' processes
util/map.o as an implicit rule and if util/map.o exists
make considers the 'util/map.o' target as done and  wouldn't
nest into Makefile.perf.

Adding FORCE for '%', because that's what we want to nest
into Makefile.perf for any target.

Adding Makefile into phony targets, because make tries to
rebuilt it and it's also resolved as '%' target.
