* libtool.m4 (archive_cmds, archive_expsym_cmds) [solaris*]: Changing

no_undefined_flag from `-z text' to `-z defs' (see entry below at
2001-04-11  Alexandre Oliva  <aoliva@redhat.com>) has a problem.
when linking a shared library with gcc calling /usr/ccs/bin/ld (eg.
the gcc supplied with Solaris 8 companion CD), using the flag
-no-undefined, shared library linking will always fail because of
the unresolved symbols from libgcc.a.  Consequently we have to
provide a path to libgcc.a when linking shared libraries in
conjunction with -no-undefined!
