Support 16k page size builds

[414owen]

I've used GHCup on an ARM M2 macbook pro, running asahi linux (fedora).

These systems have a hardware page size of 16k, rather than the usual 4k.

This seems to result in an error, if libraries compiled for a 4k page size are loaded:

haskell-language-server-9.12.2: error while loading shared libraries: libHSlibyaml-clib-0.2.5-6e0554ece1b66e21ade87fa9add75f36061ef7fc9fec3b9310c286a3c8cd9e8f-ghc9.12.2.so: ELF load command address/offset not page-aligned\n"

Specifically, ELF load command address/offset not page-aligned leads me to this conclusion.

The cpu flag that gcc would use to target my machine, seems to be:

-mcpu=apple-m2+crc+aes+sha3+fp16

Of course, it's entirely possible that something else funky is going on...

@bgamari told me during ZuriHack that this might be a bug/issue in GHC.
