Before this patch, if you wanted to add a crate to the build system you had to change about 100 lines across 8 separate makefiles. This is highly error prone and opaque to all but a few. This refactoring is targeted at consolidating this effort so adding a new crate adds one line in one file in a way that everyone can understand it.
