cleanup and fix Make.defaults
Reorder variables in Make.defaults so that they are grouped by functions. Also fixed ifeq (x,y) to have required syntax and make it work for ARCH amd64->x86_64 renaming on BSD. Also provides top-level Makefile with a "mkvars" target that displays effective variables. Signed-off-by: David Decotigny <decot@googlers.com>
