The stack trampoline generated by the sparc32 native version of
setup_rt_frame() calls sigreturn(), not rt_sigreturn(). This will
crash the task if it's ever used. (glibc sets its own restorer, so
was not affected.)
The sparc64 compat implementation has the right syscall number.
This is untested; I have no way to run a sparc32 kernel.
