If an input config file contains CONFIG_FOO=n the output one
will contain a line '# CONFIG_FOO is not set'. merge_config.sh
should not report it as difference because the end result of
CONFIG_FOO being disabled is achieved.

Inexistence of CONFIG_FOO (because of unment dependencies) in case
CONFIG_FOO=n is requested, should also be ignored.

[Problem 1]

The behaviour is inconsistent
between =n and "is not set".



 Requested: CONFIG_FOO=n
 Actual   : missing due to unmet dep

     -> suppress the report


 Requested: CONFIG_FOO is not set
 Actual   : missing due to unmet dep

     -> show the report



[Problem 2]

This patch introduces another consistency
because line 148 may report something similar.
