REBUILDS only marks clean as being out of date.
It doesn't add it to the list of targets to be
updated.

You could try this:

rule gen-ucfg ( target : source : properties * )
{
    common.Clean $(target) : file.c ;
}

The effect is to append common.Clean to the
list of updating actions for $(target).
Thus, if updating $(target) succeeds,
file.c will be deleted.
