Subject: Refinement by Stefan Krah (see issue 11715, msg133194) to exit early
 if the dpkg-architecture command is not found on $PATH.  This should fix the
 failures on FreeBSD and Solaris, which do not create the target file via I/O
 redirection if the command isn't found (unlike Linux and OS X which do).
