  just to be clear, yes, there are numerous output lines from
defconfig files, but a simple entry in a defconfig file can never
*contribute* to something being flagged as bad or unused.  all those
lines represent is the subsequent global search once something *has*
been flagged as unused or bad, just to show where it occurs anywhere
in the tree (which is sometimes informative).

  if a variable occurred *only* in defconfig files, it would be
ignored and nothing would be printed for it.  but if that defconfig
output has no value, i can toss it.
