libtool: Forward slash escaping check on Windows
Without cygpath, Window's 'cmd' may hang with a single slash (when
transforming)
and may hang with two slashes (when not transforming).
Reported: https://savannah.gnu.org/support/index.php?110901
* build-aux/ltmain.in: Use one or two slashes with Window's command
prompt based on cached value in lt_cv_cmd_slashes.
* m4/libtool.m4: Cache whether one or two slashes are needed with
Window's command prompt, when cygpath is not installed in path.
