This is to ensure that only stuff found in the chroot will be used,
and to avoid some stupid problems with libtool scripts. Therefore only
templates that have $base_chroot set can be built without the chroot.
As bonus now all messages are prepended with "[chroot]" when xbps.sh
is running inside of it.
