Thanks for sharing your configuration!  Based on that I was able to
narrow down the configuration parameter which makes SPL 2016.09-rc1 now
work on my allwinner,sun5i-r8 board as well:

	+CONFIG_USE_PRIVATE_LIBGCC=n

When I don't set it explicitly I get 'CONFIG_USE_PRIVATE_LIBGCC=y' in
my .config.  Could it be that it was set to 'n' by default in previous
releases?

Thanks,
Marcus
