Subject: [PATCH] kbuild: make -s option take precedence over V=

'make -s' should be really silent. However, 'make -s V=1' prints noisy
log messages from some shell scripts.

Of course, the combination of -s and V=1 is odd, but the build system
needs to do the right thing even if a user gives strange input.

If -s is given, KBUILD_VERBOSE should be forced to 0.
