The tools/ directory uses a different build system, and the format of .cmd files is different because the tools builds run in a different work directory. Supporting two formats compilicates the script. The only loss by this change is objtool. Also, rename the confusing variable 'relative_path' because it is not necessarily a relative path. When the output directory is not the direct child of the source tree (e.g. O=foo/bar), it is an absolute path. Rename it to 'file_path'. os.path.join(root_directory, file_path) works whether the file_path is relative or not. If file_path is already absolute, it returns it as-is. I used os.path.abspath() to normalize file paths. If you run this script against the kernel built with O=foo option, the file_path contains '../' patterns. os.path.abspath() fixes up 'foo/bar/../baz' into 'foo/baz', and produces a cleaner commands_database.json.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
