Yes, irqbench only works on x86, as far as I know.

Yes, using FPU in Xenomai applications only works with VFP. The Xscale
FPU support is unimplemented.

It does not really make sense to try this configuration, since the
Xscale fpu support is unsupported. Though I think it should exit with an
error instead of doing what it currently does.
