[tree-ssa] libmudflap and OS without a libdl.* library like darwin

[Andrew Pinski]

Your patch broke the ssa-branch's bootstrap:
2003-03-31  Frank Ch. Eigler  <fche@redhat.com>

         * Makefile.am (AM_CFLAGS): Remove optimization flags.
         (HOOKOBJS): Remove dlopen hook.
         (libmudflap_la_LIBADD): Add -ldl.
         * mf-hooks.c (dlopen): Remove hook.
         * mf-impl.h (__mf_dynamic): Ditto.
         * mf-runtime.c (__mf_resolve_dynamics): Ditto.
         * Makefile.in: Regenerated.

because libmudflap now depends on libdl.* which
I do not have on my PPC darwin (Mac OS X) machine.

Yes I can build the libdl for darwin, but I think gcc should be able to
bootstrap on other platforms without a libdl.* library.

Thanks,
Andrew Pinski
