m68k-stub.c patch, putpacket() should wait for ACK

[jtc@redback.com (J.T. Conklin)]

This is a re-send of a patch I sent back in March.  It wasn't
rejected, but it wasn't integrated either.  See the gdb-patches
archive for a more detailed rationale for this patch.  

This also fixes the comment before putpacket() in the sh stub.

	* m68k-stub.c (putpacket): Restore code so that packets are sent
 	until an ACK is received.
