I do intend as part of toplevel cleanup following up on removal of 
deprecated targets to cleanup such cases relating to targets removed from 
GCC (since whether or not any bit of the src repository supports them, 
GCC-specific configure code for them certainly isn't needed at toplevel).

Those look like newlib-target issues, not MMIX-target issues, in any case.

It's not a matter of "expected to be maintained", it's a matter of targets 
only being different from other targets where there is a clear reason for 
that difference (an important feature of the GNU toolchain is consistency 
between targets).  I expect most users of many targets to be using 
--enable-languages=c,c++ (or just c) - but I see no reason for the 
defaults for this target to be different from those for many other 
newlib-using targets.
