Bug 1258618 - Serialize substs/configs and defines bools as '1' or '' in config.status. r=nalexander This allows to use True and False as values given to set_config/set_define in moz.configure files, while postponing having to deal with the long tail of things depending on the values from substs and defines. Ideally, everything would handle the bools just fine, but there are too many things involved to deal with this right now: scripts using buildconfig.{substs,defines}, scripts using ConfigEnvironment (e.g., ConfigEnvironment itself, etc.
