The liboil Makefile will use "-mcpu=vfp" when building for ARM.
The VFP is only available for a few ARM CPUs at the moment, so this breaks the liboil build. A patch is available upstream which only enables "-mfpu=vfp" if "--enable-vfp" is given to "configure". Autotools needs to be run for liboil for this to take effect. A new configuration BR2_VFP_FLOAT is added to allow enabling vfp. If this is "yes", then "-mfpu=vfp" is added to CFLAGS.
