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.
