Hi all,
When bootstrapping gcc 4.1.1 on my AMB64 system, I run into some
troubles that seem to be connected to the linker not finding 32-bit
versions of some libraries by the available C compiler (gcc 4.0.3 on
Kubuntu). This is the place where the make process breaks down:

As I am not really interested in the biarch capability anyway, I am
looking for a way to direct the bootstrap process to skip all that
and just build me a 64-bit capable compiler. Ideally, there would be
a ./configure flag to prevent building a biarch compiler.
I looked in the docs but I cannot find an easy way to do this.
Does anyone know how this can be done?
Cheerio, Sidney
