Currently, users requiring a 64k MAXPAGESIZE can specify `-z max-page-size=65536`. Modifying the default necessitates consensus among toolchain maintainers and vendors. Will GNU ld implement a similar change? (@Nelson1225)

Nevertheless, I advocate for aligning our default with other RISC targets, especially considering the industry's shift towards larger page sizes.

Implementing this change will require extensive test updates, a time-consuming process. Thank you for taking this on:)
