The simple console driver is intended for test suite output:

https://docs.rtems.org/branches/master/c-user/configuring_a_system.html#configure-application-needs-simple-console-driver

Polled input seems to be not implemented or the missing clock driver is 
a problem. With

#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER

the scanf() should work.
