This may be worth doing, however, two points to consider.
1. If we look to change build system this may not be worth doing unless
a compelling need becomes obvious in the short term. In the meantime,
for cases where it is needed...
2. libraries can already access the includes from drivers or other
places fairly easily, just by adding the relevant "-I" flag to the
CFLAGS for that lib.
That said, since the work is already done developing this, and if it
doesn't hurt in terms of build time, I suppose we might as well merge
So tentative ack from me, subject to testing and feedback from others.
