Cheesy kconfig stuff:

 - silent/quiet/verbose build:
   - ct-ng by default only prints quit messages, such as "CC xxx",
   - if using V=0, nothing is printed,
   - if using V=1, the full command lines are printed,
   - other values are indeterminate,
   - should help in debugging the kconfig stuff;
 - complete kconfig/{,m}conf generation:
   - fully dynamic dependencies on source files,
   - compilation of .c into .o, then linking (instead of direct linking),
   - VPATH usage when not --local;
Typo + a coment moved.
