RTEMS crt0.c patch

[Joel Sherrill <joel@OARcorp.com>]

Recent modifications to gcc have made it reference more
symbols by default.  The RTEMS dummy crt0.c tries to 
satisfy these all so autoconf's link test works.

OK to commit?

        * libc/sys/rtems/crt0.c: Add even more symbols so gcc() can link
        dummy programs.
