patch: fix "make dist" when "make all" has not yet been run

[Ben Pfaff]

tests/libpspp/ll-test and other built objects are in TESTS, which
is in EXTRA_DIST.  This forces "make dist" to try to make those
targets.  However, if a full "make" has not yet run, then that
fails because gl/libgl.la hasn't yet been built (and won't be
built by that target, unfortunately).  

We don't really want to distribute those files anyway, so I
checked in the following to distinguish between tests that should
be distributed and those that should not:
