I don' think so. The reason is the same as why FireTOS does not set the _CPU 
cookie: The ColdFire just does not fit into this "level" scheme. And actually 
it is not real 68000 compatible, so not setting the cookie at all follows the 
logic of other cookies like not setting _VDO when no st-compatible video is 
present.

The information for the actual system should already be present in the _MCF  
cookie. Using the compiler flags to setup similar information for the compile-
time options IMHO does not make much sense, as all the libraries are only 
compiled for -mcpu=5475.
