-march=armv4t works for ARM processors using the ARMv4T architecture
revision. The cortex A9 in an omap4460 uses the ARMv7 architecture
revision. So, you should pass -march=armv7 instead, or -mcpu=cortex-a9

the argument to the --host option should not include the leading
dash.

the variable xenomai_root should probably be an absolute path. And
note that if you downloaded xenomai-3 from its git repository as
opposed to its latest archive, you also need to call autoreconf -i
to create the configure scrippt.
