[PATCH] Fix building with autoconf version older than 2.60.

[PATCH] Fix building with autoconf version older than 2.60.

[Andreas Schneider]

From: Andreas Schneider <asn-a6JcYMd0PQ1abyy8hY48cw@public.gmane.org>

AC_PROG_SED is only avaliable in recent autoconf versions.
Use AC_CHECK_PROG instead if AC_PROG_SED is not present.

Looks fine...

The AC_PROG_SED in the later versions of autoconf do quite a bit more
to verify that sed actually works, but our use of sed is very simple in
cifs-utils so this should be ok.

I'll plan to commit the patch in a day or two if no one objects.

Thanks,
