But 64KiB pages have already been mentioned, so sanctioning this possible
size in binutils (or LD specifically) would be a reasonable thing to do at
this time IMHO.

FWIW out of the plethora sizes (from 1KiB up to 256TiB) possible to have
in hardware (and available on a page-by-page basis) the MIPS/Linux port
has settled on a fixed for a given kernel configuration page size choice
among 4KiB, 16KiB, 64KiB, and this has been reflected in binutils, so
perhaps copying the MIPS bits might be the path of least resistance.
