PATCH: Make gdbserver use async I/O on Linux

[Daniel Jacobowitz <dmj+@andrew.cmu.edu>]

The only problem I can think of that this might cause is if F_SETOWN is less
portable than FASYNC.  Apparently you need to do that explicitly on a Linux
target before SIGIO will be sent.

This lets C-c on the host be properly handled, stopping the target.

Jim, I must be seeing double, but I think this output is already
handled in the -re directly below the one you changed.
(Ok I am jet-lagged, so excuse me if I am wrong).

	-re ".*unrecognized option.*for a complete list of options." {
	    untested "Skip mi tests (not compiled with mi support)."
	    remote_close host;
	    return -1;
	}
	-re ".*Interpreter `mi' unrecognized." {
	    untested "Skip mi tests (not compiled with mi support)."
	    remote_close host;
	    return -1;
	}
