unlike .qmake.cache & co., the presence of this file has no magic effects on where mkspecs, modules and other things are searched. as the obvious name "cache" is of course already taken, we call it "stash". the file is searched up to the super cache (if present), otherwise up to the normal cache/conf (if present), otherwise up to the root. if it's not found, it is created next to the super cache (if present), otherwise next to the cache/conf (if present), otherwise in the current output directory. note that the cache really should be created and populated by the top-level project if there are subprojects: otherwise, if there is an "anchor" (super/cache/conf), subprojects would race for updating the cache and make a mess. without an "anchor", each subproject would just create its own cache, kind of defeating its purpose. this is no different from the existing "cache", but it's worth mentioning that removing the "anchoring" function does not remove the "nesting order" constraint.
