No it isn't, HAVE_HWFP is an fpu implementation and the soft fpu check
would be duplicate in xsave.c. Also, the HAVE_HWFP macro is local in
i387.c and would have to be exported in a header file then, which
somehow taints the api.

So I rather tend to this patch than implementing fpu code in xsave for
a small or no benefit.
