qemuarm update

Would it make sense, would it be possible, for the qemuarm machine to emulate ARMv7a instead of ARMv5?

It certainly is possible, I think there are even some "qemuarmv7" machine files out there which do this.

The main reason we've stuck with qemuarm being v5 was to help the testing matrix since armv7 gets good coverage on real hardware, if we stop building v5 with qemuarm, I suspect it will bitrot...

Cheers,
