gold: running tests in parallel

[Ralf Wildenhues]

Hello,

so far all tests below gold/testsuite (and the two in gold/) are run
serially.  While arguably their creation takes up most of the 'make
check' time, the patch below allows running them in parallel, too.
Results will be summarized in gold/{,testsuite/}test-suite.log.

You could even interleaved compilation and testing by (GNU sed-y)
  sed -i 's/check_PROGRAMS/EXTRA_PROGRAMS/g' gold/testsuite/Makefile.am

for more parallelism, at the expense of slightly less readable stdout.

I did a casual look over testsuite/Makefile.am to see that tests do not
scribble over each others files, but not a thorough search.  Are there
dependencies between the tests that I overlooked?

Thanks,
Ralf
