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.

-The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
-also use the environment variable KCONFIG_ALLCONFIG as a flag or a
-filename that contains config symbols that the user requires to be
-set to a specific value. If KCONFIG_ALLCONFIG is used without a
-filename, "make *config" checks for a file named
-"all{yes/mod/no/def/random}.config" (corresponding to the *config command
-that was used) for symbol values that are to be forced. If this file
-is not found, it checks for a file named "all.config" to contain forced

This enables you to create "miniature" config (miniconfig) or custom
config files containing just the config symbols that you are interested
