Installing gmp and mpfr libraries on your build host should do it.
They only need to be linked in to the compiler for it to be able to do
constant folding reliably at compile time - you don't have to go and
fetch their source and cross-compile it for the target.
Is this any different from needing a working native compiler, Unix
tools, math library and ofher bits that you already need to be able to
build the other versions?
At most we could put a special thing into CT to check for extra build
dependencies if you're building gcc-4.3, but it seems from the message
that the configure script already does this and reports extensively,
so why bother?
