Currently, when running on the host, the output from the inferior is
mixed with the MI output. If you would like to separate the output you
can use the -inferior-set-tty command. This means that your front end
needs to be capable of creating a pty pair. That way, all of the
inferior output will be captured on a seperate descriptor.

The 'target' in teh above sentence I believe is refering to when GDB is
using a remote protocol to a specific piece of hardware. It's not
refering to the host.
