Nor when doing a cross build it seems.  The _Qp_* opts are causing me no
end of trouble trying to build a --host=--target=sparc64-x-freebsd5
(after building a --host=i386-x-freebsd5 --target=sparc64-x-freebsd5 compiler)

I am only able to get a successful build if I enable HARD_QUAD in

I have searched around quite a bit and I cannot find good explanation of
hard-quad-float and soft-quad-float as it applies to UltraSparc [only].

Am I hitting a known cross build problem?  Is gcc/config/sparc/freebsd.h
in error?  Since I am targeting only UltraSparc, should I just turn on
HARD_QUAD for all?
