	* Makefile.in (objc): Don't build objc-runtime, must be done later.
	(distclean): rm float.h.
	* config/float.h-ieee: New file.
	* config/float.h-vax: New file.
	* i386/t-go32 (LIBGCC1, CROSS_LIBGCC1): Define as null.
	* i386/xm-go32.h: New file.
	* config.sub: Recognize go32* and sim* as os's.
	* configure: Handle float_format.
	(i[345]86-*-go32): Define xm_file and tmake_file.
	(LIBGCC2_FLAGS): Define inhibit_libc if cross compiler.
