Hi Abe,

Support for cross compiling RT is precarious. There were some attempts
in the past, but not very successful, so I normally just build
natively.

Chris B (CC'd) is working on that part for Darwin / ARM [1], but we
should also get something working for Linux (if that's what you need).
As soon as his integration work finishes we can try some magic on our
side.

If you could try his new scheme (using runtime dir instead of
projects), it may make the process smoother later on. Also, feel free
to pick up on the task, if that interests you, as I'll only have time
to look at that in a few months from now...

I'm also copying Saleem and Jon that have worked around this topic
more than I did, and can help with more info.

cheers,
