Here is a simple hack for killing broken devices which were (now
nominally) configured in a previous line.  Something like this should
be used to avoid moving correctly placed devices in /sys/conf/NOTES
to many MD NOTES files just because they are broken for 1 arch, or
even to put almost all devices in /sys/conf/NOTES and kill selected
ones in MD notes files.  Options could be killed similarly.  A non-hackish
version would use a new keyword.  A slightly less hackish version could
use a count of -1.  config somehow already handles devices that are
configured more than once reasonably allthough it adds them more than
once in newdev().
