It turns out if you define CONFIG_SERIAL_SOFTWARE_FIFO that the call to serial_buffered_init() is lib_ppc/board.c, even though the implementation is compiled out elsewhere. The following batch fixes this case, assuming I understand the situation correctly. This matches the useage of the macro in the cpu/ppc4xx/serial.c file.

* Don't call serial_buffered_init() is CONFIG_SERIAL_SOFTWARE_FIFO ~ is defined to be 0.
