Sorry for the digression then. But the point about DESTDIR still holds,
from my point of view.

Yes, this was the original plan, but there are still many things on our
todo list before that.

DESTDIR is used by xeno-config the same way it is used by
Makefiles. When you compiled Xenomai for a target and installed it with
DESTDIR=/home/romain/target, you have to set DESTDIR in xeno-config
environment so that it outputs
-I/home/romain/target/usr/realtime/include and
-L/home/romain/target/usr/realtimeLib.
Since it is a rather obscure functionality, it probably deserves an
explanation.
