CONFIG_DEBUG_UART is enabled in defconfig, but there's no Low-level
debugging functions implemented, so build fails because of undefined
references to `printch' in common/console.c.
In order to fix this, enable CONFIG_DEBUG_LL.

You're right. No UART driver is specified in defconfig, thus
DEBUG_UART_ALTERA_JTAGUART is incorrectly selected by default.
In fact, firefly-rk3288_defconfig got broken after the following commit
was applied:

    commit 220e8021af96741bd7149ca9895e1f0c8a38d0bb
    Author: Thomas Chou <thomas@wytron.com.tw>

        nios2: convert altera_jtag_uart to driver model

Yes, chromebook_jerry_defconfig has exactly the same problem.
