help building x86_64->i686 cross-compiler

[Tupshin Harper <tupshin@xxxxxxxxxxx>]

I'm running a debian amd64 (pure, not biarch/multiarch), and I'm trying 
to build gcc that is able to compile regular x86 binaries (as in):
checking host system type... i686-pc-linux-gnu
checking build system type... x86_64-unknown-linux-gnu

but it fails with the following:
checking for main in -lm... configure: error: Link tests are not allowed 
after GCC_NO_EXECUTABLES.
make[2]: *** [configure-target-libstdc++-v3] Error 1
make[2]: Leaving directory 
`/usr/src/vexi/core/upstream/gcc-3.4.2/build-i686-pc-linux-gnu'

anybody have any suggestions?
