Add ARMHF architecture compatability

[TartanSpartan]

Some users use ARM processor devices (ARM and also ARM64) , but the gcc functionality associated with the build scripts will not allow them to compile Vita-compatible programs on these devices. Even simple C test programs fail to pass the build process (running cmake) in this use case. This would be very useful for developing on the go, and on e.g. Rasberry Pi machines.
