On barebox-next, I get:
board/freescale-mx25-3-stack/built-in.o: In function `go':
3stack.c:(.flash_header_start+0x0): undefined reference to `_start'
board/freescale-mx25-3-stack/built-in.o: In function `imx25_3ds_fec_init':
3stack.c:(.text.imx25_3ds_fec_init+0x4): undefined reference to `mc34704_get'
3stack.c:(.text.imx25_3ds_fec_init+0x1c): undefined reference to
`mc34704_reg_write'
I guess this change also needs:

Say Y here if you are using the Freescale MX25 3stack board equipped
with a Freescale i.MX25 Processor
