Good catch.  The problem extends to octave as well. I suspect everywhere
$system was used before, we should be using some variant of $host instead.

grep '$system' cf/*.ac
cf/java.ac:            case $system in
cf/octave.ac:case "$system" in

I have changed the above $system variables to $host_os and also the
corresponding test strings to what is appropriate.

For everybody's information here are examples of the $host variable
variations for my system.

grep host Makefile
host_triplet = i686-pc-linux-gnu
host = i686-pc-linux-gnu
host_alias =
host_cpu = i686
host_os = linux-gnu
host_vendor = pc

Here is what we have done elsewhere:

grep '$host' cf/*.ac
cf/c++.ac:    case "$host_os" in
cf/csiro.ac:    case "$host_cpu" in
cf/pthread.ac:    case "$host_os" in
cf/python.ac:AM_CONDITIONAL(darwin_os, [case "$host_os" in darwin*) true;;
*) false; esac])
cf/summary.ac:system:           $host

I don't know much about it, but I presume the cf/csiro.ac logic using
$host_cpu is appropriate because the mieee flags are compiler AND cpu
dependent.

In cf/summary.ac I have just changed the "system:" label to
"host:" since system now seems to be a misnomer.
