[PATCH 01/26] perf tools: Add automated make test suite

[Jiri Olsa]

Adding automated test for testing the build process.
To run it you need to 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_clean_all: cd . && make -f Makefile clean all
    test: test -x ./perf
  - make_python_perf_so: cd . && make -f Makefile python/perf.so
    test: test -f ./python/perf.so
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf
  - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=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 successfull build
and for existence of several built files. Additional
after-build checks could be added.
