* tests/touch/relative: Likewise.
* tests/touch/Makefile.am: Include $(top_srcdir)/tests/check.mk,
to get the parallel-"make check" bits.

Move a slow test into tests/misc.

* tests/check.mk: Wrapper.
* tests/ls/time-1: Move this file to tests/misc/ls-time.
* tests/misc/ls-time: New file.  From tests/ls/time-1.
