That is a fair assesment.

 From memory, gdbserver uses very little from tm-*.h and *-tdep.c.  The 
main thing is the description of the remote protocol G packet.  I think 
that protocol packet should be published (it is a GDB interface) in a 
way that lets both GDBSERVER and the *-tdep.c files use it.

I don't know that trying to split the tdep file will actually help that 
much.  I've tried building GDBSERVER using the bloat technique - gave up 
when I found something was trying to suck in top.c ....
