Subject: Define SUBTARGET32_DEFAULT_CPU on FreeBSD

Support for the i386 cpu has been removed from FreeBSD 6.0 onward and
thus i486 instructions can be used by default. A similar change has been
applied to the version of GCC supplied with FreeBSD:
http://svn.freebsd.org/viewvc/base?view=revision&revision=198344

I don't have commit access so feel free to commit this when approved.

    * config/i386/freebsd.h (SUBTARGET32_DEFAULT_CPU): Add.
