Peter Maydell 78bfef72fb linux-user: Handle rt_sigaction correctly for SPARC ...

SPARC is like Alpha in its handling of the rt_sigaction syscall:
it takes an extra parameter 'restorer' which needs to be copied
into the sa_restorer field of the sigaction struct. The order
of the arguments differs slightly between SPARC and Alpha but
the implementation is otherwise the same. (Compare the
rt_sigaction() functions in arch/sparc/kernel/sys_sparc_64.c
and arch/alpha/kernel/signal.c.)

Note that this change is somewhat moot until SPARC acquires
support for actually delivering RT signals.
