Subject: [PATCH] Makefile: allow building selected tests with non-NPTL toolchain

Some architectures are still stuck with non-NPTL toolchains.
These are for example ARC, Blackfin, Xtensa etc.

Still rt-tests are very good benchmarks and it would be good to enable use of
at least selected (those that will be built) tests on those architectures.

This change makes it possible to only build subset of tests that don't require
NPTL calls.

By default behavior is not modified - all tests are built, but if one wants
to build with non-NPTL toolchain just add "HAVE_NPTL=no" in command line
or modify "HAVE_NPTL" variable right in Makefile and execute "make".
