    build: suppress GNU ld warning about RWX load segments
    
    We cannot really avoid such and we're also not really at risk because of
    them, as we control page table permissions ourselves rather than relying
    on a loader of some sort. Present GNU ld master started warning about
    such, and hence 2.39 is anticipated to have this warning.
