[PATCH 01/27] perf tools: Add automated make test suite

[Jiri Olsa <jolsa@redhat.com>]

Adding automatd test for testing the build process.
To run it you needto be in perf directory or specify
one with PERF variable. It's also possible to specify
optional Makefile to test via MK variable.

Whole suite is executed twice, the second time with
O=/tmp/xxx option added.

To run the whole suite:
  $ make -f tests/make
  MAKE_PURE: cd . && make -f Makefile
  TEST: test -x ./perf
  MAKE_DEBUG: cd . && make -f Makefile DEBUG=1
  TEST: test -x ./perf
  ...

You see command line for 'MAKE_PURE' test right away,
and the output is stored into MAKE_PURE file.

To run simple test:
  $ make -f tests/make MAKE_DEBUG
  MAKE_DEBUG: cd . && make -f Makefile DEBUG=1
  TEST: test -x ./perf

At this moment tests checks for succesfull build
and for existence of several built files. Additional
after-build checks could be added.
