Did some digging of my own I can report that indeed things aren't working
well for powerpc. I tried updating gdbserver to 12.1 and 13.1. 12.1 was
much the same as 11.2. 13.1 reported that it was unable to send sigkill
when processing the interrupt command. 13.1 also seems not to be able to
respond to the 'info os processes' command from the gdb client
