* Makefile.in (OPTIONAL_BACKENDS): Add lynx-core.o.
* bfd-in2.h (tdata): Add lynx_core_data; * config.bfd configure.host: Get rid of superfluous netbsd and lynxos entries. * configure.in: Add lynx-core.o to Lynx config. * i386lynx.c: Add defs for core file support. * lynx-core.c: New file with Lynx core file support. * hosts/i386lynx.h: Move lots of host specific includes to here. Add def of HOST_LYNX. Remove unnecessary defs.
