Some content in Makefile.in is removed because after this change, the scripts no longer invoke the preprocessor and thus don't have unknown dependencies anymore outside what is provided in their inputs array. The order of exports.PREFERENCES in properties-db changes because the data file has shorthands placed after longhands. The only usage of it is in test_css-properties-db.js which doesn't care about the order. MozReview-Commit-ID: AMjzTRf2HYN
