arm-xilinx-eabi is a compiler without glibc or uclibc. Xenomai needs
glibc or uclibc, so can not be compiled with arm-xilinx-eabi.
arm-none-linux-gnueabi is fine. However, you may want to find a
toolchain for Zynq with glibc, because the Zynq has an FPU, and
arm-none-linux-gnueabi (usually) uses soft floats, so is not an
optimal choice for Zynq.
