[okl4-developer] Console output on Iguana

[Jamie Lennox]

Thanks to a couple of the okl guys for this. 

For anyone else interested kdb output is (partially) in
platform/pc99/pistachio/kdb/io.cc and putc_serial and putc_screen do as
advertised, so you can change this in the kdb config options or as
suggested to me just put a putc_screen(c) within putc_serial to print to
both.

Thanks for your help everyone

Jamie
