Jeff,

Thanks for the great hints.

Of course what I really want is to trigger the other library when linking with 
-pg rather than -m<something>.  But I think I can do that by hacking on the 
specs file -- I have the local host's specs file to refer to.

(Of course I now need to _write_ an mcount implementation, and convince the 
binutils to compile up a cross-gprof and ...)

Thanks again,

Richard.
