Adds the necessary support bits to libgcc.  All other mainstream
i386/amd64 targets already have this.

Tested on i386-unknown-openbsd5.2 and x86_64-unknown-openbsd5.2.
Fixes a couple of testcases.


libgcc/:

2012-10-06  Mark Kettenis  <kettenis@openbsd.org>

	    * config.host (i[34567]86-*-openbsd* and x86_64-*-openbsd*):
	    Add to list of i[34567]86-*-* and x86_64-*-* soft-fp targets.

gcc/:

2012-10-06  Mark Kettenis  <kettenis@openbsd.org>

	    * config/i386/openbsdelf.h (LIBGCC2_HAS_TF_MODE, LIBGCC2_TF_CEXT) 
	    (TF_SIZE): Define.
