Hi Peter,
I don't think our config would be of a lot of general use. And I don't
feel confident enough to mess with the existing tcl scripts, but will
look into this a bit more if I get time.

Yes my workaround works fine, but the documentation is wrong at present;
the definition/export of $_TARGETNAME does not work at all AFAICS.
I do seem to recall lpc2478.cpu did not work either ("not defined"
somehow).
