    buildgcc: Deal with gmp on 32bit Linux on 64bit CPUs

    GMP is overeager to detect 64bit ABIs even if the entire running codebase is
    32bit (but on a 64bit CPU). Enforce a 32bit build in that situation.
)
building GMP can not detect Cygwin is 32bit either if the
host which Cygwin is running is 64bit. We set ABI=32
in that case.
