No.  Any use of $target would be wrong in Zsh.  

The handling of --build, --host, and --target was a real mess in
autoconf =< 2.13, but now it's crystal clear:

  --build  is the arch on which you build,
  --host   is the arch on which the program will run
  --target is used *only* when building compiler tool-chains and specifies the
           arch for which they should produce output.

There are A LOT of configure.in out there that erroneously use
$target in lieu of $host.
