[ARM] 3107/3: ARM EABI: last bits to configure it
Patch from Nicolas Pitre This adds the configuration option, and disables any FPA floating point emulators which are not EABI compatible. It also disables Acorn RISC OS/Arthur binary support when CONFIG_EABI=y since it is incompatible with an EABI kernel.
