"xargs -n1 basename" will execute basename even if there are no lines
piped into it, causing a "basename: missing operand" error if no
packages are installed, which will happen for the target portion of
buildtools-tarball.
(xargs' -r option could have been used here, but it is a GNU extension
and I thought it best to avoid that for the sake of future
interoperability).
