Mike Hommey fe76207882 Bug 1036645 part 2 - Make using a separate config.cache the default for AC_OUTPUT_SUBDIRS. r=gps
All subconfigures are essentially doing it already, so just inverse the process. That would also limit problems with additional subconfigures (all the recent ones had to come with their own config.cache)
