📄 Description

Reverts change of build architecture back to sandybridge from btver2, as something that the new architecture included is causing issues with Rosetta 2 on M1 CPUs.
Add -mtune=generic to make sure build is optimized for generic CPU instead of Sandy Bridge specifically. -march will limit the instruction sets to use and -mtune will determine how to micro-optimize.

Should fix https://github.com/shadps4-emu/shadPS4/issues/2750 (no idea if the game will actually work but it should fix the provided crash, beyond that much I think it should be a compatibility report)
