GCC3.3.3: building cross compiler powerpc-linux undefined symbol

[Gazelle Jean-Laurent <jean-laurent dot gazelle at thalescomputers dot fr>]

Hi,

I tried to build my cross compiler from the 3.3.3 released version of GCC.
First I've already built 686-pc-linux-gnu --> powerpc64-linux. OK.

Now that I'm trying with target=powerpc-linux, the compilation fails with undefined symbol.
Here is my config.status file :
../gcc-3.3.3/configure --with-gcc-version-trigger=/CrossCompiler/gcc-3.3.3/gcc/version.c --host=i686-pc-linux-gnu --enable-languages=c,c++ --target=powerpc-thales-linux --enable-altivec --disable-nls --with-sysroot=/opt/cross-linuxppc32-3.3/include_glibc2.2.5-139 --with-libs=/opt/cross-linuxppc32-3.3/lib_glibc2.2.5-139 --prefix=/opt/cross-linuxppc32-3.3 --program-prefix=ppc32-33- --with-headers=/opt/cross-linuxppc32-3.3/include_glibc2.2.5-139

Here is the compilation error :
gcc   -g -O2 -DIN_GCC -DCROSS_COMPILE  -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long   -DHAVE_CONFIG_H  -o cc1 \

Maybe I do something wrong but I can't see my mistake. It looks like the compilation search for AIX symbols ???
So if someone already experienced this problem, or if you have an idea of what is wrong...

thanks,
