configs/freescale_mpc8315erdb: remove U-Boot build
Binutils was locked down to 2.24 because U-Boot 2014.01 didn't build with more recent binutils. However, this doesn't work anymore because binutils 2.24 is deprecated. Current U-Boot 2016.09.01 doesn't work out of the box because the u-boot-nand.img support has been removed. Since updating U-Boot is generally not needed anyway, we just remove the U-Boot support.
