conf/,gcc-common.inc: Add support for ARM hard float toolchain
Rename ARM_FP_MODE to ARM_FP_ABI
Set target fpu to hard for hardfp ARMv7
Use machine override to add base package arch instead of appending to
OVERRIDES directly
Pass --with-float option to gcc configure taking into account
what float ABI is selected through ARM_FP_ABI
