You'd first need to figure out how the gcc scripts set the gmp host
type. Is gmp's config.* involved in any way? If all else fails, you
could try hacking the configure script in the gmp tree, to hard code all
host-related variables and ignore whatever is passed in from outside.

Well said.  I just hope I can figure this out.

It seems more likely to be an issue with the gcc build scripts.
I don't think that GMP and MPFR can or should do anything.

Well yes, it is. However given that the problem occurs within the gmp
and mpfr source builds I felt it can not hurt to ask here.  Given that
no one seems to know what to do really.
