Fixed bug #16861.

touch sets wrong atime or mtime when they are not specified.
touch silently failed when HAVE_UTIME is not defined.
(This needs more consideration. Which platform does not support it?)
# Derick, after HAVE_UTIME issue is resovled, this should be merged.
# or we can just merge 1st problem for now.
