debootstrap prior to 1.0.67 generated an empty sources.list during
foreign bootstraps (Debian#732255 [1]). Fall back to the git checkout
if the installed debootstrap version is too old.

v2→v3:
  - fix unbalanced white space around pipes
  - replaced GNU-specific version sort option with POSIX compliant set
    of options

Like -V, -C is not available on OSX either. Maybe use "-c"? If so, I can fix it
when applying.

Thanks for the pointer. So Apple took a 2005 version of GNU sort,
removed version sort support (introduced in 1997) and neglected to
update it for POSIX.1-2008 compliance [1]?

Guess using "-c" and redirecting stderr to /dev/null is our only option
then. Feel free to fix that up when applying.

Thanks for pointing out these portability issues!
