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.

# U-boot build supports generating object files in a separate external

# 1) Add O= to the make command line
|

|

# 'export BUILD_DIR=/tmp/build'

# 'make'
