PATCH: minor testsuite cleanup

[Jeff Sturm]

While poking through the testsuite configuration, it occurred to me that
qthreads doesn't really exist, and libgc/libz are now only convenience
libraries.  Removing them here unclutters the output of "runtests -v" a
little bit.

OK?

2003-09-03  Jeff Sturm  <jsturm@one-point.com>

	* lib/libjava.exp (libjava_arguments): Remove unneeded variables.
	(test_libjava_from_source): Likewise.
	(test_libjava_from_javac): Likewise.
