e513588f75 microblaze: use generic syscalls.h
The prototypes in syscalls.h all make sense for
microblaze, but for some of them, the actual implementation
in sys_microblaze.c needs to be adapted.

3183e06863 microblaze: clean up signal handling
When legacy signal handling is disabled, the
arch/microblaze/kernel/signal.c implementation can
be much simpler, as most of it is handled generically
from kernel/signal.c.

This is also a prerequisite for using the generic
asm/unistd.h, which does not provide __NR_sigreturn,
because this macro is referenced by the current signal.c
implementation.

a6029d1c8c microblaze: prepare signal handling for generic unistd.h
We need to define set_restore_sigmask() in order to
get pselect and ppoll. Also, the setup_frame function
can not be used when __NR_sigreturn is not defined.
