Ok, now that I come to think about it, enabling CONFIG_XENO_HW_FPU with
CONFIG_VFP unconditionally uses VFP instructions during the context
switch. Since this configuration does not make sense for any of the
armv4 and armv5 processors supported by Xenomai, we will add a check at
runtime so that xenomai will refuse starting in that case.
Regards.
