Makes sense to me. John is working on the next spin of rt-tests so I
CC'd him to pull in this change.

(resend with a sane emailer)
I think we have to NAK this one.
I saw this problem too, if you try to do an individual build, hackbench 
and rt-migrate fail unless the lib rttest has already been built.
The thing is, neither hackbench nor rt-migrate use any of the functions in 
that lib rttest, so I'd rather not put a false dependency on the lib where 
it isn't needed.

If you'd like to come up with a patch that separates it out of the default 
libs to solve the problem, I'd accept that.

Thanks!
