Bugfix: Use the custom build settings name if passed when printing current setting being used.

The message, such as:
  Building fss_read using 'settings' with modes 'monolithic', 'thread'.

Should instead be:
  Building fss_read using 'settings.main' with modes 'monolithic', 'thread'.

Use the custom settings name if the custom build arguments are passed to display the correct name.
