I agree that there definitely needs to be some error reporting (and not
only here but in many more places, look e.g. at conf_write() or
conf_write_autoconf()), but why use conf_warning() for this? It will
prefix the error message with "include/config/auto.conf:<last lineno>",
which has nothing to do with the path that could not be opened.
