Any specific reason why you want to use gcc 6.x / glibc? We normally
don't do that in our defconfigs, and gcc 5 / uClibc works here with a
quick test - So I've removed it.

I was going to drop this EXT2_BLOCKS, but I did a test build and the
kernel config indeed enables so many modules that they don't fit in our
default size, so I've added a comment about that and committed, thanks.
