There's three issues:

1. The code which selects which file to install as /etc/pkg/FreeBSD.conf
doesn't recognize a fake branch name and installs the "latest" file instead
of the "quarterly" file.

2. The branch name gets into /bin/freebsd-version, which is technically
correct, but confuses freebsd-update's "don't update files if the only
change is the version number" code.

3. The branch name gets into every single .o file in the kernel build, and
at this point all hell breaks loose.
