I don't think this patch makes much sense unless I am misunderstanding
the description of the problem. The entire point of this script is to
parse the .cmd files that kbuild generates and those are only present
in the build directory, not the source directory, so we should never be
looking in there, unless is its default value, which is
the way the script is currently written. Your patch would appear to
either make use do way more searching than necessary (if the build
folder is within the source folder) or miss it altogether (if the build
folder is outside the source folder).

I think the help message probably needs to be updated to be a little

args = parser.parse_args()
Let me know if this makes sense or if I am completely off base :)
