I'd prefer an explicit list in the Makefiles rather than tagging.  Under no
circimstances should we be munging these on the way to /usr/include
though since we still can have symlinks pointing to the sys tree...

In other words, I'm fine with the kernel parts of /usr/include being
a *subset* of whats in the kernel tree.  But not different to it.

Part of the reason why its done like it is right now is that nobody really
got around to figuring out what was needed and doing the Makefile lists
and testing that it didn't break stuff.

Cheers,
