target_to_host_sigset_internal is required.
do_sigreturn is correct in using target_to_host_sigset_internal, because
get_user already did the endianness conversion.

Laurent's qemu-m68k git tree, but according

do_rt_sigreturn forgets to initialize the signal mask variable before
trying to use it to restore the mask, so the signal mask is undefined
after do_rt_sigreturn. This bug has been in all the time since
7181155d when do_rt_sigreturn was implemented for m68k.
