* configure.host: Recognize i[34]86-sequent-*. 

* trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
	return from bfd_seek indicates an error.
	New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
	TRAD_CORE_STACK_OFFSET.
	* hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
	TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
