testsuite fix for remote targets

[Mark Salter]

This change:

        * config/monitor.exp (gdb_target_cmd): Abstracts some of the
        code from gdb_target_monitor, so it can be used independantly
        for gdbserver.

apparently broke some remote targets. I'm not sure how this worked at
all, but following is a simple patch that fixes the problem I'm seeing.
