builder: cache C and assembly file outputs

Browse Source 
This probably won't speed up the build on multicore systems (the build
is still dominated by the whole-program optimization step) but should be
useful at a later date for other optimizations. For example, I intend to
eventually optimize each package individually including C files, which
should enable cross-language optimizations (inlining C functions into Go
functions, for example). For that to work, accurate dependency tracking
is important.
