bug#18406: O_NOATIME patch

[starlight . 2014q3]

Wrote a quick (but clean) patch
to have O_NOATIME applied on file opens.
I find this handy for bulk find/grep when
I'd prefer not to update atime.

If the patch is of interest I'm willing
to improve it by having the feature
present conditionally on the appearance of
   HAVE_WORKING_O_NOATIME
in 'config.h'.

Perhaps my choice of -N  or
--no-atime are not agreeable to
all.  Possibly the option does
not belong under "miscellaneous."
Easy to change.
