The GSoC Monkey project is also interested in this so I will figure it
out and post what I find. I suspect with some configuration changes the
rtems-test command in the rtems-tools repo could run the executables.
The RSB builds and installs the rtems-tools package.

Sorry I thought there was some reference to the git sha1 in libbsd.txt
and that is what I could not find.

Yes it is the latest and I have pushed the change to the RSB. To use the
RSB to build qemu do ...

 $ cd bare
 $ ../source-builder/sb-set-builder --prefix=/opt/rtems/qemu devel/qemu

... setting the prefix to something suitable for your development host
machine.

This builds cleanly on FreeBSD 10.1. I have not run it yet.
