I am trying to compile version 4.4.1. Host gcc has the same version.

I run the configure script as follows:
../src/configure --build=x86_64-unknown-linux-gnu
--host=x86_64-unknown-linux-gnu --target=powerpc64-unknown-linux-gnu
--prefix=$(BUILDDIR)/cross-tools --disable-werror --disable-checking
--with-sysroot=$(SYSROOT) --enable-languages=c,c++ --disable-multilib
--disable-nls

No, I checked, LD_LIBRARY_PATH is not set in the environment.
It seems that this error occurs when the host gcc has same version as
version of compiled cross-gcc, because I have also tried the
following:
- compile sysroot cross compiler (x86_64 -> x86_64) version 4.5.
- compile minimum linux system (including gcc) using that compiler
- when in this new system I am trying to compile another cross
compiler (x86_64->powerpc64) the same error is occurs, but caused by
/bin/sh instead cc1, because bash was linked with same version of
libgcc_s.so.1. As in the first case, the error occurs immediately
after the appearance libgcc_s.so.1 in the obj/gcc directory.
I've successfuly compiled cross-gcc by adding the -disable-shared
option, but I would not want to abandon the shared gcc libraries
