x86: change /dev/console to tty to fix job control
Job control is turned off because it cannot obtain controlling terminal on /dev/console, so it is impossible to do any job control operation behind real x86 device (keyboard+monitor or virtualized). This patch switches /dev/console to tty devices for ash on x86 generic target. Signed-off-by: Jiri Slachta <slachta@cesnet.cz> SVN-Revision: 37693
