Testsuite: do not use `chmod -R' when cleaning up. * tests/Makefile.am (clean-local-check): Do not use `chmod -R' on the test directories, as that may change or try to change the mode of installed files: the test directory may contain symlinks to ltmain.sh files from a Libtool installation, and Solaris `chmod -R' touches symlink targets. Instead, use the cleanup strategy used in distdir.am (which is also employed in tests/defs.in). Signed-off-by: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
