That assumes that all C code behaves the same on CONFIG_DEP=""
and CONFIG_DEP="n".

Formally that is not true, because "#ifdef CONFIG_DEP" will behave
differently.  A quick grep of the kernel source:

  grep -r '#.*if.*def.*CONFIG_'

... finds 10,000 such lines!  Although most of them are booleans
that will never have a value of "".
