This isn't going to work because you need to run the BBB executables on
real hardware.
This will require setting up a way (tftp or SD card) to get the rtems
executables on the BBB.

rtems-test takes more arguments and you will have to give it some
that is specific to how your board and boot server are setup.

This looks to be the correct way to build rtems but not run the BBB

Hopefully someone will pipe up who is actively using the BBB. I am speaking
from patterns and old experience.
