Good idea.

FWIW, I didn't think this would affect MIPS in any way, given that
I couldn't find a single bug report for any of these targets in
bugzilla.  I don't mean open bugs, I mean, any, ever, other than
build failure issues.  I don't recall anyone mentioning anything
related to these targets on the gdb or gdb-patches lists, ever,
either.  It seems like google searches for these targets only hit
the gdb documentation, and my suggestion to remove them on
the gdb@ list [1].  :-)

Also, I thought of MIPS's earlier focus on MDI, and knowing that
even that one was pushed out of tree years ago, my thinking was
that the risk of this affecting anyone in practice
approximates zero.
