    loader: Test GCC cross builds as part of universe.sh
    
    Sicne we have gcc15 in Jenkins, and since people are actually using it,
    add cross building tests to universe.sh to avoid build breakage when
    hacking on loader.efi (and others). UEFI makes it too easy to mix
    pointers and integers since it deals in an odd mix of
    EFI_PHYSICAL_ADDRESS and pointers...
