Automake patch to not assume egrep

[Paul Eggert]

I just checked in this patch to remove an "egrep" that snuck back into
the Automake sources recently.

2002-06-26  Paul Eggert  <address@hidden>

        * Makefile.am (maintainer-check): Don't assume that egrep exists;
        this fixes a portability bug introduced in the 2002-06-08 fix for
        PR automake/317.
