[Bug target/16627] New: "Unrecognized opcode" error while building cross compiler for powerpc

["gkyla at central dot ntua dot gr" <gcc-bugzilla at gcc dot gnu dot org>]

My machine is (uname -a): 
 
Linux kentri 2.6.7-gentoo-r11 #5 Mon Jul 19 07:26:39 EEST 2004 i686 Intel(R) 
Pentium(R) M processor 1500MHz GenuineIntel GNU/Linux 
 
I use (gcc --version): 
gcc (GCC) 3.3.3 20040412 (Gentoo Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6) 
as a native compiler. 
 
configure options for gcc were: 
../gcc-3.4.1/configure --target=powerpc-ibm-aix4.3.2.0 --prefix=/usr/local 
--enable-languages=c 
from within directory /home/cross/gcc-3.4-aix. 
 
I have already installed binutils-2.14.90.0.8 in /usr/local using the same 
"--target" configure option (and nothing else), plus all the 
necessary /usr/include headers from a nearby powerpc machine 
in /usr/local/powerpc-ibm-aix4.3.2.0/include. 
 
Build was initiated with a plain "make" inside /home/cross/gcc-3.4-aix. 
 
The last lines of the build before it fails are: 
 
/home/cross/gcc-3.4-aix/gcc/xgcc -B/home/cross/gcc-3.4-aix/gcc/ 
-B/usr/local/powerpc-ibm-aix4.3.2.0/bin/

Tell me if there is any more info I should provide.
