Thanks for your answer; i'm building on i686.

Actually, i discovered 2 items in GCCs' bugzilla:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11621
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21999

The answer was

 "You configured/built in the gcc subdirectory.
  You need to configure/build in the top level directory."

Hrm. Now i'm trying to figure out, how this applies to
crosstools in my case.

GCC is correctly configured from the top:

+ echo 'Build gcc-core w shared libgcc'
Build gcc-core w shared libgcc
+ mkdir -p build-gcc-core-shared
+ cd build-gcc-core-shared
+ test '!' -f Makefile
+ /home/peter/cross_gcc/crosstool-0.38/build/powerpc-860-linux-gnu/gcc-4.0.1-glibc-2.3.5/gcc-4.0.1/configure
--target=powerpc-860-linux-gnu --host=i686-host_pc-linux-gnu
--prefix=/opt/crosstool/gcc-4.0.1-glibc-2.3.5/powerpc-860-linux-gnu
--with-local-prefix=/opt/crosstool/gcc-4.0.1-glibc-2.3.5/powerpc-860-linux-gnu/powerpc-860-linux-gnu --disable-multilib
--with-cpu=860 --enable-cxx-flags=-mcpu=860 --without-headers --disable-nls --enable-symvers=gnu --enable-__cxa_atexit
--enable-languages=c --enable-shared

Then libiberty.a is created correctly in the directory "/build-gcc-core-shared/libiberty":

if [ x"-fpic" != x ] && [ ! -d pic ]; then \
  mkdir pic; \
else true; fi
touch stamp-picdir
if [ x"-fpic" != x ]; then \
  gcc -c -DHAVE_CONFIG_H -g -O2  -I.

And that's it. I don't see the error...
