[PATCH] Don't try to use help2man when cross-compiling

[Colin Watson]

John Taylor reported that this patch fixes one of his problems in
http://savannah.gnu.org/bugs/?27349. It's been a while since I had
anything to do with Autoconf's cross-compiling support, so does this
look reasonable? The "cross_compiling" variable was added in a
considerably older version of Autoconf than we already require.

        * configure.ac: Don't look for help2man when cross-compiling.  Fixes
        part of bug #27349.
