kconfig: Add error handling to KCONFIG_ALLCONFIG
- Only try to read the file specified if KCONFIG_ALL_CONFIG is set to something other than the empty string or "1". - Don't use stat to check the name passed to conf_read_simple so that zconf_fopen can find the file in the current directory or in SRCTREE removing a extremely source of confusing failure, where KCONFIG_ALL_CONFIG was not interpreted with respect to the directory make was called in. - If conf_read_simple fails complain clearly and stop processing. Allowing the simple debugging of typos. - Clearly document the behavior so it is clear to users which values are treated as flags and which values are treated as filenames. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
