cross-compiling problems (linux to ppc)

Hello,
My host is a linux x86 RedHat machine.
My Target is Linux PowerPC  machine.

Now , I had followed the instructions on :
http://penguinppc.org/embedded/cross-compiling/
the only diffference I had made was added the "--prefix=/opt/ppc"
so that it will insatll it in a different directory (because
I need also original binutil and gcc to compile for x86 linux targets).


what I did is :
downloaded latest release tars of binutils and gcc.

for binutil:
I created a toplevel build directory and from there:

./configure --target=powerpc-linux --prefix=/opt/ppc
make
make install

and it went OK.

Now , fior gcc:
I created a toplevel build directory and from there:
./configure --target=powerpc-linux --prefix=/opt/ppc --disable-shared
--disable-threads --enable-languages=c --with-newlib

I get immediately the following mesage:
../gcc-3.3.2/configure --target=powerpc-linux --prefix=/opt/ppc
--disable-shared --disable-threads --enable-languages=c --with-newlib |more
Configuring for a i686-pc-linux-gnu host.
*** This configuration is not supported in the following subdirectories:
    target-libstdc++-v3 target-libf2c target-libffi target-boehm-gc
target-zlib target-libjava zlib fastjar target-libobjc
   (Any other directories should still work fine.)

but it finishes the ./configure command.

Then , in make , I get after some time the following error messages:

if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

Needless to say, but still , I have signal.h under /usr/include ,
/usr/include/linux, and in some other
locations

sting
