I will approve it, though honestly Makefile.variables was currently arranged
from most likely to be changed, meaning the further you go down the file, the
less likely it is that you will need to change a value, while things like
DIST_BRANCH, UPSTREAM_BRANCH, VERSION_ON_UPSTREAM, and BUMP_RELEASE are
frequently changed.
