Hand-list the two-step assym.h -> .[Ss] -> .o dependencies. The

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.

The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.

This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on.  You can still screwed really easily, so continue running make
depend as config tells you.

Idea from a discussion with drahn
ok drahn, kettenis likes the idea too
