config.rpath port to POSIX 1003.1-2001 hosts

[Paul Eggert]

gettext 0.12.1's config.rpath uses "egrep", but that command has been
removed from POSIX as of POSIX 1003.1-2001, so it's officially more
portable to use plain grep.  Here's a patch.

2003-06-17  Paul Eggert  <address@hidden>

        * config.rpath: Use grep instead of egrep, since POSIX 1003.1-2001
        no longer requires egrep.
