From e75e5879c0e8d232a2e8f045685beeb8c965aba4 Mon Sep 17 00:00:00 2001
From: David Kalnischkies <david@kalnischkies.de>
Date: Sun, 6 Dec 2015 14:03:35 +0100
Subject: replace "which" with "command -v" for portability

which is a debian specific tool packaged in debianutils (essential)
while command is a shell builtin defined by POSIX.

Closes: 807144
Thanks: Mingye Wang for the suggestion.
