libtool.m4 port to POSIX 1003.1-2001 hosts

[Paul Eggert]

Two non-POSIX usages snuck into libtool.m4.  Here's a patch to make
it portable again, to POSIX 1003.1-2001 hosts.  Such hosts don't
support "test -a", or "egrep".

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

        Port to POSIX 1003.1-2001 hosts.
        * libtool.m4 (_LT_AC_LANG_CXX_CONFIG): Don't use egrep.
        (AC_LIBTOOL_PROG_LD_SHLIBS): Don't use "test -a".
