[M3devel] more cm3cg on Raspberry Pi

[Jay K]

> cm3cg: sorry, unimplemented: -mfloat-abi=hard and VFP

drat. I'll try to cross build a boot archive, but I should see the same thing.
Maybe the support is not in mainline? And we should port it from some Raspberry Pi place?
Or maybe those last switches aren't needed?
Or maybe just give up and stick with C?
