    kconfig: Add error handling to KCONFIG_ALLCONFIG · 5efe241e
    Eric W. Biederman authored
    - 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.
