scripts: merge_config: Add option to suppress warning on overrides
Currently merge_config.sh will unconditionally warn if a fragment overrides
any already set symbol. This is generally desirable but is inconvenient in
cases where we want to create a fragment which disables unwanted options in
the base configuration, for example when attempting to produce a smaller
version of another configuration.
Add an option -Q which will suppress these warnings.
