Update bmake glue to build GCC 4.2.

Also:
        Switch FreeBSD to use libgcc_s.so.1.

        Use dl_iterate_phdr to locate shared objects' exception frame
        info instead of depending on older register_frame_info machinery.
        This allows us to avoid depending on libgcc_s.so.1 in binaries
        that do not use exception handling directly. As an additional
        benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.

        Build newly added libgomp.so.1 library, the runtime support
        bits for OpenMP.

        Build LGPLed libssp library. Our libc provides our own
        BSD-licensed SSP callbacks implementation, so this library
        is only built to benefit applications that have hadcoded
        knowledge of libssp.so and libssp_nonshared.a. When linked
        in from command line, these libraries override libc
        implementation.
