This commit adjusts some files to use Kbuild.include.
- Use cc-option defined in Kbuild.include (Delete cc-option in config.mk) - Use cc-version defined in (Delete cc-version in config.mk) - Move binutils-version and dtc-version to Kbuild.include by analogy to cc-version
This commit also adds srctree (same as SRCTREE) to use Kbuild scripts.
