	* reloc.c (BFD_RELOC_SWREL32, BFD_RELOC_SWREL64): Define.
	(BFD_RELOC_ALPHA_LINKAGE, BFD_RELOC_ALPHA_BASEREG): Define.
	* targets.c (bfd_target_evax_flavour): Define.
	(evax_alpha_vec): Declare.
	(bfd_target_vector): Add ecoffalpha_little_vec and evax_alpha_vec
	if BFD64 is defined.
	* bfd-in2.h, libbfd.h: Rebuild.
	* Makefile.in: Rebuild dependencies.
	(BFD64_BACKENDS): Add evax-alpha.o, evax-egsd.o, evax-etir.o,
