[PATCH] Get rid of host <signal.h> in config/tm-linux.h

As pointed out by Daniel Jacobowitz in his Linux/MIPS patch, including
the host <signal.h> in the tm.h file makes no sense. This moves it to
the nm.h file and leaves reasonable defaults for REALTIME_LO and
REALTIME_HI in tm-linux.h.
Daniel, I think this should make it possible for you to include
tm-linux.h instead of copying over the relevant bits in
config/mips/tm-linux.h.
Checked in.

Index: ChangeLog
from Mark Kettenis <kettenis@gnu.org>
* config/tm-linux.h: Do not include <signal.h>. Instead provide
reasonable defaults for REALTIME_LO and REALTIME_HI if they're not
already defined.
* config/nm-linux.h: Include <signal.h>.
[__SIGRTMIN] (REALTIME_LO, REALTIME_HI): Define to __SIGRTMIN and
(__SIGRTMAX + 1) respectively.
