re PR ada/16592 (Ada tools don't use the newly built shared libraries)

	* s-asthan-vms.adb: Removed.

	* s-asthan-vms-alpha.adb: Added.

	* Makefile.in [VMS] (LN,LN_S): Define as cp -p
	Rename s-asthan-vms.adb to s-asthan-vms-alpha.adb.
	[VMS]: Add translations for g-enblsp.adb.
	(LIBGNAT_SRCS): Add seh_init.c.
	(LIBGNAT_OBJS): Add seh_init.o.

	PR ada/16592

	Link all gnat tools with -static-libgcc, since
	-shared-libgcc is now used by default on some systems (e.g. linux with
	recent binutils).
	Remove references to Makefile.prolog/generic, no longer used.
