configure problem in libstdc++-v3 (biarch cross gcc for x86_64)

[Lothar Werzinger <lothar at xcerla dot com>]

I have a problem compiling a gcc (cross) compiler.
 
I have a build machine which is linux-x86_64. There I can create x68_64 
excutables with -m64 and i686 executables with -m32.
 
I want to build a (cross) compiler that is a i686 executable (so that I can 
run it on i686 machines as well as x86_64 machines. And it should be able to 
generate code for both architectures with -m32/-m64, so the target would be 
x86_64 with multilib enabled. The targets are full SuSE Linux systems, so 
there is no need in building glibc.

I attached a script I use to configure and build binutils and gcc. The point 
where I get stuck is libstdc++-v3. There I get the following error:

checking for main in -lm... configure: error: Link tests are not allowed after 
GCC_NO_EXECUTABLES.
make: *** [configure-target-libstdc++-v3] Error 1

Any help appreciated!

Here's the log for libstdc++-v3:
