Subject: [RFC PATCH 0/3] kbuild: Unmet dependency warning

Hi,

The first patch in this series adds a warning to the kbuild system when
options that are selected have unmet dependencies.

The subsequent patches show two simple examples that were spotted by the
first patch.

In the view of the ARM defconfig story, such patch would help with
ensuring that a platform Kconfig selects the necessary options.

Thanks.
