# ARM needs a sane minimum architecture. We need the `yield`
# opcode, arm6k is the first iteration that supports it. arm6k
# is also the first Raspberry PI generation and older hardware
# is likely too slow to run the game. We're not enforcing the
# minimum architecture, but if you're build for something older
# like arm5 you need to remove the `yield` opcode. It's set in
# Qcommon_Mainloop() in frame.c via inline assmebly.
