Pb cross-compilation sous Debian

Bonjour,

Je travaille sous Debian Etch AMD64 et je souhaite compiler pour
l'architecture i386 (et pour powerpc ultérieurement). Le problème est
que je n'arrive pas à compiler GCC pour i386.

après avoir installé les paquets nécessaires, j'exécute les étapes
suivantes:


$ apt-get source gcc-4.1
$ cd gcc-4.1-4.1.1ds2
$ export GCC_TARGET=i386
$ debian/rules control
$ dpkg-buildpackage -rfakeroot -b > ../gcc.build 2>&1 || echo 'Build error'


j'obtiens le message d'erreur suivant:

J'ai cherché sur Google, mais je n'ai trouvé aucune information pouvant
m'aider et c'est pourquoi je sollicite votre aide.
