Interesting...

You're right.  "make allyesconfig" works, but "make allnoconfig" doesn't.

The ENABLE_* symbols are derived form the CONFIG_* symbols (via a sed 
invocation in the makefile).  There's a "CONFIG_FEATURE_SUID" guard, and 
"CONFIG_FEATURE_SUID_CONFIG" (what a name) is an option under that.  And the 
include/config.h file doesn't include a comment about that not being defined 
unless the guard is defined...

It's a config dependency issue.  For the ENABLE_ guards to work, they all have 
to be defined (albeit 0), and the config.h stuff that's built off of is 
optimizing out branches.

How do we go about fixing the config stuff so it prints the "not defined" 
comments for all symbols, even the ones implied by other symbols?
