[9fans] Hosted Inferno on Raspberry Pi

[Graham Gallagher]

The gcc flags: -march=armv6 -mfloat-abi=softfp -mfpu=vfp, will let you
compile the standard Inferno emu-g on the Raspberry Pi first go. Not
all the Linux VT interface ioctls are supported by the video driver so
a little work is needed to incorporate the framebuffer device.
