Incidentally, all of gcc's hooks into softfloat should probably be in
the public symbol namespace instead of FBSDprivate.  The compiler generates
references to them, so we cannot claim that they are internal, unsupported
interfaces.  I assume that moving them will not break the ABI because
FreeBSDprivate includes FBSD_X, but I haven't tested this.  Any objections
to moving them?  Affects arm and mips.
