The complex macro, config_filename, was introduced to do: [1] drop double-quotes from the string value [2] add $(srctree)/ prefix in case the file is not found in $(objtree) [3] escape spaces and more [1] will be more generally handled by Kconfig later. As for [2], Kbuild uses VPATH to search for files in $(objtree), $(srctree) in this order. GNU Make can natively handle it. As for [3], converting $(space) to $(space_escape) back and forth looks questionable to me. It is well-known that GNU Make cannot handle file paths with spaces in the first place. Instead of using the complex macro, use $< so it will be expanded to the file path of the key. Remove config_filename, finally. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
