Scott, Joey, dpkg-shlibdeps seems to be confused. On i386, sparc,
s390, amd64 (and soon powerpc), we have libgcc1 as 32bit and as 64bit
library. My current workaround doesn't seem to work anymore:

[ -d debian/lib64gcc1 ] && mv debian/lib64gcc1 debian/lib64gcc1.saved
dh_shlibdeps \
        -Llibgcc1 \
        -Llibgcj6 \
        -l:debian/tmp/usr/lib:debian/libstdc++6/usr/lib:debian/libgcj6/usr/lib:debian/libgcc1/lib \
        -pgij-4.0 -plibgcj6 -plibgcj6-awt
[ -d debian/lib64gcc1.saved ] && mv debian/lib64gcc1.saved debian/lib64gcc1

Any hints, how to pick up the correct library, or ignore 64bit libs,
when generating dependencies for 32bit binaries, and vice versa?
