Description:
If trying to run the command line client specifying both --no-defaults and --defaults-file, instead of an error about the options conflicting, the second option will be listed as unknown:

 root@cc882c7bf057:/pack# mysql --no-defaults --defaults-file=/tmp/test.cnf
 mysql: unknown variable 'defaults-file=/tmp/test.cnf'

Same issue occurs on 5.7.11, with a slightly different error message

How to repeat:
* Install server and client
* Run mysql --no-defaults --defaults-file=/something
