Makefile: Support three levels of verbosity
At present the EC Makefile supports two levels of verbosity:
V unset: Show an abbreviated build log (operation and file only)
V=1: Show the full build log, including all commands
However, even the abbreviated build log includes a lot of output. It is
basically a long list of filenames and is of little use during
development. It is more useful to show just warnings and errors.
Add a new setting, V=0, which provides this.
BUG=chromium:680243
BRANCH=none
TEST=emerge-reef chromeos-ec; test each of V=, V=0, V=1 and see that the
Makefile does the correct thing.
