tests/Makefile.am patch for 'configure; make distclean' (fyi)

[Paul Eggert]

In an already-clean distribution, 'make distclean' fails because
tests/Makefile invokes ./testsuite, which doesn't exist.
This is such a small thing that I hope it's OK that I just went
ahead and installed the following patch.

2001-10-05  Paul Eggert  <address@hidden>

        * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
        doesn't exist.  Remove *.tmp, as a .tmp file is created during the
        build of $(TESTSUITE).
