Well this is no longer a GCC question but rather a GMP question and you should
ask in their mailing list. But when built inside GCC, the following configure
options are passed to GMP:
--build=${build_alias} --host=none-${host_vendor}-${host_os} \
--target=none-${host_vendor}-${host_os}

It depends on if you built them as shared libraries are static libraries. If
as shared, 99% sure you don't need to rebuild all 4, just GMP.
