By having this as a Python script rather than a host executable, this should simplify the build process on non-Unix platforms. With this change, pyelftools is now required to build Zephyr. Please consult the getting started documentation for your host platform for installation instructions. Jira: ZEP-2062 Signed-off-by: Leandro Pereira <leandro.pereira@intel.com>
