Clean up stale dependencies after r320278

Browse source 
Our current approach to dependency tracking cannot cope with switching
generated asm syscall stubs into C wrappers. Perpetuate the hack in
Makefile.inc1 to paper over the problem until we can take a holistic
approach to fixing dependency problems.

fashion. This prevents many of the common foot-shooting actions in the
upgrade as well as the limited ability to roll back the kernel across
the ino64 upgrade. Complicated use cases may not work properly, though
enough simpler ones work to allow recovery in most situations. There is an
issue with dependencies which may not properly rebuild everything needed
when doing a NO_CLEAN build. Removing *stat*o in lib/libc obj tree is
sufficient to avoid this issue.
