* i386dynix.c, config/i386-dynix.mt: New files, handling Dynix
variant of a.out.
* configure.in, config.bfd: Use them for Dynix.
* Makefile.in: Add dependencies for i386dynix.o.
* targets.c: Add definition for i386dynix_vec.
* hosts/symmetry.h: Do not define TRAD_CORE_USER_OFFSET for Dynix.
Define HOST_DATA_START_ADDR and TRAD_UNIX_CORE_FILE_FAILING_SIGNAL
for Dynix. Remove inclusion of dynix3.h, Dynix bfd is now handled by
i386dynix.c
Mon Mar 28 12:53:27 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* Makefile.in (BFD32_BACKENDS): Add coff-sparc.o.
