kbuild: make -s should be used with kernelrelease/kernelversion/image_name
If .config has been edited, there will be a silentoldconfig run:
$ make defconfig
...
$ make kernelrelease
scripts/kconfig/conf --silentoldconfig Kconfig
3.16.0-rc1+
Recently, kbuild started to print the name of the build directory when
using O=
$ make O=build kernelrelease
make[1]: Entering directory `/dev/shm/mmarek/linux-2.6/build'
3.16.0-rc1+
Since these targets are often used in scripts, add a hint to use make -s
to the help text.
