Summary: As Aaron suggested, there are quite some problems with our Makefile and scripts. So in this diff I did some cleanup for them and revise some part of the scripts/makefile to help people better understand some mysterious parts. Test Plan: Ran make in several modes; Ran the updated scripts. Reviewers: dhruba, emayanke, akushner Differential Revision: https://reviews.facebook.net/D12285
