Rename selftets/vm to selftests/mm for being more consistent with the
code, documentation, and tools directories, and won't be confused with
virtual machines.

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the related file to use "grep -E" instead.
sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests`
Here are the steps to install the latest grep:
wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
tar xf grep-3.8.tar.gz
cd grep-3.8 && ./configure && make
sudo make install
export PATH=/usr/local/bin:$PATH

Add build/cross-build dependency check script kselftest_deps.sh
This script does the following:
Usage: ./kselftest_deps.sh -[p] <compiler> [test_name]
kselftest_deps.sh [-p] gcc
kselftest_deps.sh [-p] gcc vm
kselftest_deps.sh [-p] aarch64-linux-gnu-gcc
kselftest_deps.sh [-p] aarch64-linux-gnu-gcc vm
- Should be run in selftests directory in the kernel repo.
- Checks if Kselftests can be built/cross-built on a system.
- Parses all test/sub-test Makefile to find library dependencies.
- Runs compile test on a trivial C file with LDLIBS specified
in the test Makefiles to identify missing library dependencies.
- Prints suggested target list for a system filtering out tests
failed the build dependency check from the TARGETS in Selftests
the main Makefile when optional -p is specified.
- Prints pass/fail dependency check for each tests/sub-test.
- Prints pass/fail targets and libraries.
- Default: runs dependency checks on all tests.
- Optional test name can be specified to check dependencies for it.
To make LDLIBS parsing easier
- change gpio and memfd Makefiles to use the same temporary variable used
to find and add libraries to LDLIBS.
- simlify LDLIBS append logic in intel_pstate/Makefile.
