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.
