Bug 1402012 - Create config.statusd directory; r=glandium The config.statusd directory is created alongside config.status, which contains the same information but is split across many files instead of all in a single file. This allows the build system to track dependencies on individual configure values. MozReview-Commit-ID: 2DbwKCJuNSX
