>How-To-Repeat:
1. Run Debian 8, install necessary building prerequisites.
2. Download sets from here: http://ftp.netbsd.org/pub/NetBSD/NetBSD-7.0.1/source/sets/
3. Extract sets and cd usr/src.
4. sudo ./build.sh -m evbarm -a earmv7hf -u release
5. (After receiving the above errors, try again with 'su' instead of 'sudo')
