allarch: Set empty TARGET_PREFIX and TARGET_FPU

* set empty TARGET_PREFIX
  This has a bit weird reason caused by unsupported setup where
  external-toolchain is used in some DISTRO only for some MACHINEs
  and internal is used for other MACHINEs.
  Because external-toolchain usually comes with different TARGET_PREFIX
  it was causing allarch recipes to have different signatures even
  when they don't use toolchain at all.
  Empty TARGET_PREFIX also helps to find allarch recipes which still
  have default dependency on e.g. virtual/${TARGET_PREFIX}gcc.
* add TARGET_FPU just for completeness (it was used in icecc.bbclass
  but now it's vardepexcluded there as well)
