abuild: ensure a package has deps before printing them
After the first dep is printed, `shift` is called to avoid the special case where the first dep cannot have a comma prepended. However, if there are no deps for a package (seen early on in the aports main repo in acf-jquery), $# is 0. POSIX specifies that `shift` has two options when the shift operand (1) is greater than $#: - if non-interactive, it can exit the shell - if it does not exit the shell, it must return a non-zero exit code Since we run the shell with -e, the second case folds in to the first. BusyBox ash does not implement this behaviour, but bash does when called as /bin/sh or when the `posix` shopt is set.
