am335x_evm_defconfig is a 32bit ARM board. You need to install the appropriate cross-compiler. On Ubuntu:

sudo apt-get install gcc-arm-linux-gnueabi

When building you need to reference the cross-building tools:

make mrproper
make am335x_evm_defconfig
make CROSS_COMPILE=arm-linux-gnueabi-

https://u-boot.readthedocs.io/en/latest/build/gcc.html has more detail.
