- Define __MAKE_CONF to allow per-arch make.conf files in buildworld

- Set the UNAME_* variables to make use of the override support in uname(1)
  This allows us to get rid of the uname shell script in the build chroots
- Collect some variables that are probably old and mouldy, for later GCing
- If FETCH_ORIGINAL is set in the environment, don't fetch from ftp-master
