How to build ARM hardfp/NEON toolchain with crosstool-ng

I'm trying to target a Cortex-a8, and want to build a single toolchain
that can be used to build both hardfp as well as NEON executables (I
don't believe I'll ever want to mix those two variants within the same

If I understand correctly, hard float for VFP3 requires
"-mfloat-abi=hard -mfpu=vfpv3" and NEON requires "-mfloat-abi=softfp

Is there a way to configure crosstool-ng to build a cortex-a8 multib
toolchain for those configurations to run on a linux-3.0 based system?
