Problems building classpath-0.98 with GCJ on MIPS

[Manuel Lauss <manuel.lauss@xxxxxxxxxxxxxx>]

Hello!

I'm running into problems trying to build classpath-0.98 on a MIPS32 target:

CFLAGS="-O2 -mips32 -msoft-float" ./configure --prefix=/opt/classpath
--build=mipsel-softfloat-linux-gnu --host=mipsel-softfloat-linux-gnu
--target=mipsel-softfloat-linux-gnu --disable-gconf-peer
--disable-gtk-peer --disable-plugin --enable-gmp
--enable-regen-headers --enable-static --enable-shared --disable-rpath
--with-gnu-ld

bugs out at:

checking for gcj... gcj -C
checking if gcj -C is a version of gcj... yes
checking if gcj -C -g works... yes
checking if gij works... configure: error: The Java compiler gcj -C -g
failed (see config.log, check the CLASSPATH?)

the log is full of these:

       return VMObject.clone((Cloneable) this);

Did I miss any prerequisites?
Any help is very much appreciated!
