Adding 'make install' and 'make install-bin' tests into tests/make. It's
run as part of the suite, but could be run separately like:

  $ make -f tests/make make_install
  - make_install: cd . && make -f Makefile DESTDIR=/tmp/tmp.LpkYbk5pfs install
    test: test -x /tmp/tmp.LpkYbk5pfs/bin/perf
  $ make -f tests/make make_install_bin
  - make_install_bin: cd . && make -f Makefile DESTDIR=/tmp/tmp.dMxePBMcFT
    install-bin
    test: test -x /tmp/tmp.dMxePBMcFT/bin/perf

Adding TMP_DEST tests/make variable to provide the DESTDIR directory for
installation tests.

Adding this to existing test targets, since DESTDIR variable 'should
not' affect other than install* targets. We can always separate this if
there's a need for DESTDIR-free build test.

Running tags and cscope make tests only if the 'ctags' and 'cscope'
binaries are installed, so we don't have false alarm test failures.

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.
