Looks like the build is actually succeeding for me now. Not sure what
happened originally when it bailed the way it did. My build must have
been in a weird state. My apologies for the false alarm. I
successfully built arm and arm64.

This means, we don't need patch 1/2 after all.

That said, and while I am a complete buildroot newbie, I do like the
suggestion of creating sub-directories for the tools and including the
makefiles from linux-tools.mk rather than relying on alphabetical
sorting.
