Hi Hector,

Thanks a lot for your time again! :)

I've converted libgcc1 package from amd64 to all using my
backported dpkg-cross 1.32 and installed it:

$ wget http://ftp.de.debian.org/debian-amd64/debian/pool/main/g/gcc-3.4/libgcc1_3.4.3-13sarge1_amd64.deb
$ dpkg-cross -a amd64 -b libgcc1_3.4.3-13sarge1_amd64.deb
$ sudo dpkg -i libgcc1-amd64-cross_3.4.3-13sarge1_all.deb
$ dpkg -l |grep libgcc
ii  libgcc1        3.4.3-13sarge1 GCC support library
ii  libgcc1-amd64- 3.4.3-13sarge1 GCC support library (for cross-compiling)

Unfortunately, it doesn't resolve my problem and I still can see
errors about "skipping incompatible" libs:
