[PATCH] Use new Linux threads support for Linux/Alpha

I've just checked in the following patch.  I've done a test build and
some minimal testing on alphaev6-unknown-linux-gnu.  There is no
Linux/Alpha GDB maintainer, so I'm regarding this as an obvious fix
since the same changes have been made to other GDB ports for GNU/Linux
running on other architectures.

	* config/alpha/alpha-linux.mh (NATDEPFILES): Use proc-service.o,
	thread-db.o, and lin-lwp.o for thread support instead of
	linux-thread.o and lin-thread.o.
	* config/alpha/nm-linux.h (PREPARE_TO_PROCEED, GET_THREAD_SIGNALS)
	(ATTACH_LWP): Define to use the following lin-lwp.c functions...
	(lin_lwp_prepare_to_proceed, lin_thread_get_thread_signals)
	(lin_lwp_attach_lwp): Declare.
