freebsd-aout.h: New, FreeBSD a.out config file.

Browse Source 
2000-09-28  David O'Brien  <obrien@FreeBSD.org>
	* config/i386/freebsd-aout.h: New, FreeBSD a.out config file.
	Contains the old contents of config/i386/freebsd.h
	* config/i386/freebsd.h: Now the ELF rather than a.out config file.
	Contains the old contents of config/i386/freebsd-elf.h
	* config/i386/freebsd-elf.h: Retire this file -- contents moved to
	config/i386/freebsd.h.
	* configure.in: Adjust for above changes.
	* po/POTFILES.in: Likewise.
	* po/en_GB.po: Likewise.
	* po/gcc.pot: Likewise.
	* configure: Rebuilt.
