Remove warnings from RTEMS crt0.c

[Joel Sherrill]

Hi,

The RTEMS crt0.c is just a stub so autoconf
will find methods.  It uses a macro to
generate stub bodies for routines we want
autoconf to find that are not in libc.
The macro that generates the stubs does
not generate a return statement with properly
typed argument.  So when you do a -Wall, you
get lots of warnings.  This just eliminates
the warnings.

OK to commit?
