BZ #127: Problem building CACAO 0.99.4 for MIPS 32 on linux

Status fields:

I was tryting to build CACAO along with some other jvm to run on ASUS WL-500G Premium
(MIPS-32 Broadcom BCM94704) running OpenWrt Kamikaze 8.09 (kernel 2.4). Using the
toolchain provided by the kamikaze i tryed to build CACAO using the GNU Classpath 0.97.2
and later the 0.98 version.

../configure --host=mipsel-linux --disable-gtk-peer --disable-gconf-peer --with-java-
runtime-library-prefix=(path to GNU classpath) --with-jni --disable-zlib --disable-zip

Running make i get a problem with cacaoh:

../../../src/classes/classes:/home/fsa/classpath98/linux/usr/share/classpath/glibj.zip
-d .java.lang.Class
/bin/bash: line 2: ../../../src/cacaoh/cacaoh: cannot execute binary file

Since i was building CACAO on Ubuntu, i tryed to build cacaoh for linux and using it
instead:

../configure --host=mipsel-linux --disable-gtk-peer --disable-gconf-peer --with-java-
runtime-library-prefix=(path to GNU classpath) --with-jni --disable-zlib --disable-zip
--with-cacaoh=(path to cacaoh)

This time when running make i get:

The build worked for me the last time I checked, plus it's easier now without cacaoh.

MIPS is a big PITA anyway, because every board seems to report signals in different and
undocumented ways.
