* Makefile.am (SUBDIRS): Remove 'tests'. (include): The '$(top_srcdir)/tests/local.mk' file. (check-root): Remove this convenience target, it's no longer needed now that the "real" check-root target once in 'tests/Makefile' will land in the top-level makefile. * configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'. * tests/Makefile.am: Rename ... * tests/local.mk: ... like this, with a lot of adjustments. * tests/init.cfg: Move ... * init.cfg: ... here. This is necessary, for a limitation of the gnulib-provided 'tests/init.sh', which unconditionally look for 'init.cfg' in the $(srcdir) directory. * tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests', not in '$srcdir', and extend $PATH with './src', not with '../src'. * tests/Coreutils.pm: Adjust similarly. * tests/pr/pr-tests.pl ($pfx): Likewise.
