- Create separate libs for each architecture. OS X doesn't need this (we just build a universal binary), but it will help Linux. - Move the libuv build stuff into wren.mk where the actual dependency on the lib is. - Download libuv to deps/ instead of build/. That way "make clean" doesn't blow it away. - Don't redownload libuv unless needed.
