Use full path including $(OUTPUT) to run tests from Makefile for
normal case when objects reside in the source tree as well as when
objects are relocated with make O=dir. In both cases $(OUTPUT) will
be set correctly by lib.mk.

Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to
indicate the test program, extended test program and test files. It is
easy to understand the purpose of these files. But mix of compiled and
uncompiled files lead to duplicated "all" and "clean" targets.
In order to remove the duplicated targets, introduce TEST_GEN_PROGS,
TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled
objects.
Also, the later patch will make use of TEST_GEN_XXX to redirect these
files to output directory indicated by KBUILD_OUTPUT or O.
And add this changes to "Contributing new tests(details)" of
Documentation/kselftest.txt.

Change from = to += in order to allows the user to pass whatever
CFLAGS they wish(E.g. pass the proper headers and librareis
(popt.h and libpopt.so) in cross-compiling)

Use the CC variable instead of hard coding gcc. Also clean up the compiler
options by creating a CFLAGS variable.

This adds make install support to selftests. The basic usage is:
$ cd tools/testing/selftests
$ make install
That installs into tools/testing/selftests/install, which can then be
copied where ever necessary.
The install destination is also configurable using eg:
$ INSTALL_PATH=/mnt/selftests make install
The implementation uses two targets in the child makefiles. The first
"install" is expected to install all files into $(INSTALL_PATH).
The second, "emit_tests", is expected to emit the test instructions (ie.
bash script) on stdout. Separating this from install means the child
makefiles need no knowledge of the location of the test script.

This adds a Make include file which most selftests can then include to
get the run_tests logic.
On its own this has the advantage of some reduction in repetition, and
also means the pass/fail message is defined in fewer places.
However the key advantage is it will allow us to implement install very
simply in a subsequent patch.
The default implementation just executes each program in $(TEST_PROGS).
We use a variable to hold the default implementation of $(RUN_TESTS)
because that gives us a clean way to override it if necessary, ie. using
override. The mount, memory-hotplug and mqueue tests use that to provide
a different implementation.
Tests are not run via /bin/bash, so if they are scripts they must be
executable, we add a+x to several.

Add the mq_perf_tests tool I used when creating my mq performance patch.
Also add a local .gitignore to keep the binaries from showing up in git
