Add procfs support for Alpha OSF/1-2.x.

	* config/alpha/nm-osf.h:  Renamed from nm-alpha.h, generic
	OSF/1 native support.
	* config/alpha/alpha-osf1.mh (NAT_FILE):  Changed accordingly.
	(MUNCH_DEFINE):  Removed.
	* config/alpha/alpha-osf2.mh, config/alpha/nm-osf2.h:  New files
	for procfs support.
