As Linus said: detect old and known to be problematic, everything else has to
be handled as "current". But see tools/firmware/ovmf-dir-remote/OvmfPkg/build.sh

    gcc_version=$(gcc -v 2>&1 | tail -1 | awk '{print $3}')
    case $gcc_version in
      4.5.*)
        TARGET_TOOLS=GCC45

        TARGET_TOOLS=GCC47

        TARGET_TOOLS=GCC48
        ;;
      4.9.*|4.1[0-9].*)
