   4 # It sets various shell variables based on the the host and the
   5 # configuration options.  You can modify this shell script without
   6 # needing to rerun autoconf.

  12 # It uses the following shell variables:
  13 #   host                The configuration host
  14 #   host_cpu            The configuration host CPU
  15 #   target_optspace     --enable-target-optspace ("yes", "no", "")
