Re: [PATCH] Makefile: add missing dependencies of 'config-list.h'

> We auto-generate the list of supported configuration variables from

> 'generate-cmdlist.sh' helper script and stored in the 'command-list.h'
> header.  Commit 709df95b78 (help: move list_config_help to
> builtin/help, 2020-04-16) extracted this into a dedicated
> 'generate-configlist.sh' script and 'config-list.h' header, and added
> a new target in the 'Makefile' as well, but while doing so it forgot
> to extract the dependencies of the latter.  Consequently, since then
> 'config-list.h' is not re-generated when 'Documentation/config/*.txt'
