Append the ".map"; don't replace the existing suffix.  For example:

  make bin/ConnectX3.mrom.map

The easiest way is to create the file config/local/general.h and #undef the 
features that you want to omit.

Unless you are short on flash space, there is no significant advantage to 
reducing the .mrom size.  The two most constrained resources are base memory 
usage (which is unaffected by removing features) and option ROM space usage 
(which is also unaffected by removing features for .mrom).
