Hi.
I couldn't find an easy way to run a subset of tests using the new
parallel machinery. I find it very convenient from time to time
to be able to specify "run all these tests in this directory in parallel".
gdb 7.6 could let me run a subset of directories in parallel
using TEST_DIRS (hacky, but it worked),
but with the new machinery we can take this further and run
any random set of tests in parallel.
This patch implements this idea.
E.g.,
bash$ make -j10 check TESTS="gdb.server/*.exp gdb.threads/*.exp"

* Makefile.in (TESTS): New variable.
(check-single): Pass $(TESTS) to runtest.
(check-parallel): Only run tests in $(TESTS) if non-empty.
