* config/tc-i960.c (ARCH_HX): Define. 

(arch_tab): Add HX.
	(targ_has_sfr): Handle ARCH_HX.
	(targ_has_iclass): Handle ARCH_HX.
	(tc_coff_fix2rtype): Add return 0 to avoid warning.
	(tc_headers_hook): If the architecture was specified explicitly,
	use it when setting the flags.  Set the extern variable coff_flags
	rather than headers->filehdr.f_flags, since the latter is set
	unconditionally in obj-coff.c.
	(i960_handle_align): Remove unused variable fixp.

Support for building bfd and opcodes as shared libraries, based on
patches from Alan Modra <alan@spri.levels.unisa.edu.au>:
