Attached is the final (but untested) patch. The difference is, that
.ver file (and corresponding t-freebsd file) have been moved to
libgcc. I modified existing solaris .ver file (as suggested by Joseph)
and sprinkled it with %if[n]defs (IMO, solaris .ver file also needs
these).

gcc/ChangeLog:

2010-08-31  Uros Bizjak  <ubizjak@gmail.com>

	* config.gcc (i[34567]86-*-freebsd*, x86_64-*-freebsd*): Add
	i386/t-fprules-softfp and soft-fp/t-softfp to tmake_file.

libgcc/ChangeLog:

2010-08-31  Uros Bizjak  <ubizjak@gmail.com>

	* config.host (i[34567]86-*-freebsd*, x86_64-*-freebsd*): Add
	i386/t-freebsd to tmake_file.
	* config/i386/t-freebsd: New file.
	* config/i386/libgcc-bsd.ver: New file.

Gerald, can you please test this patch?

Uros.
