one more sync from gnulib

[Paul Eggert]

I installed this to catch up with today's gnulib changes.
It doesn't really affect coreutils as coreutils already
does gl_FUNC_MEMCMP independently.

        * m4/argmatch.m4 (gl_ARGMATCH): Don't require gl_FUNC_MEMCMP, for the
        sake of packages that don't want to worry about ancient systems.
        * m4/memcoll.m4 (gl_MEMCOLL): Likewise.
