Hello - I am trying to work through the book "Mastering Embedded Linux
Programming" by Chris Simmonds, and trying to work through building u-boot
after having built the cross toolchain. I am running into an error when I
try to build u-boot, any ideas?

The correct cross compiler is arm-linux-gnueabihf-. I'm not sure about
yours. Also, you should give ARCH=arm option in your build.

You did not build an appropriate cross toolchain, which is in turn why
you're getting those errors.

I get a deluge of such errors with gcc-8. Use gcc-7 or earlier until
someone fixes it (or fix it yourself and send a patch).
