Failure was with a Linaro GCC 5.1.

Working was Linaro GCC 6.3.1.

I would happily use our latest SUSE GCC 7.0.1 if only U-Boot had a
private libgcc for aarch64... :(
U-Boot tries to use -lgcc for the hello_world example (which I did not
find a way to suppress other than hacking the Makefile?) and for the
final u-boot.bin.

Andreas
