[ Upstream commit a26fe287eed112b4e21e854f173c8918a6a8596d ]
The scripts/kconfig/merge_config.sh script requires an existing $INITFILE (or the $1 argument) as a base file for merging Kconfig fragments. However, an empty $INITFILE can serve as an initial starting point, later referenced by the KCONFIG_ALLCONFIG Makefile variable if -m is not used. This variable can point to any configuration file containing preset config symbols (the merged output) as stated in Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will contain just the merge output requiring the user to run make (i.e. KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make olddefconfig).
Instead of failing when `$INITFILE` is missing, create an empty file and use it as the starting point for merges.
