Precisely - you diagnosed your own problem :)  You have not configured
the uartlite driver.

do menuconfig -> kernel config -> drivers -> character -> serial:

[*] Xilinx uartlite serial port support
[*]   Support for console on Xilinx uartlite serial port

This will fix the built-in.o problem as well.

This really is a bug in the default kconfig created by
petalinux-new-platform - it should enable the uartlite by default.
I'll fix it.

Cheers,

John
