but it would not be incorrect to do so, and would more accurately
reflect dependencies.  some kind of install-if-changed mechanism instead
of tar would mitigate some of the penalty from repeated RTEMS installs.
(more effective expression of inter-directory dependencies through the
use of non-recursive make in RTEMS source tree would mitigate the rest.)

accurately reflecting dependencies all the way up from the hardware to
the end application seems like it'd be a good thing.  ideally I could go
to a single directory containing RTEMS, libraries, and application, and
type "make" and it would just "do the right thing"(tm) without having to
churn through hundreds of recursive makes.
