I _think_ from memory that this is because commands like compile_et and
so on get rebuilt (because libc is updated) and they have dependancies
on them so other files get rebuilt.  Do you get unnecessary recompiles
if you "make UPDATE=y build" yet again?

Without looking, a fix could possibly be to get compile_et to generate
it's output into a temp file and compare that with the old generated
file and only update it if it's changed.

Anyone who knows this side of the world any better got any comments?
