OK, --enable-arm-eabi fixed the latency program, but xeno-test still

Xenomai or CONFIG_XENO_OPT_PERVASIVE disabled.
(modprobe xeno_nucleus?)
BUT, neither are disabled... And, xeno_nucleus is built-in to the kernel.
Ok. If you are using an EABI toolchain, did you pass --enable-arm-eabi
to the configure script?
