Here is the relevant output building package on wheezy i386:

It seems linking issues reported a while ago are really gone, but
wrong includes are still here. And the clang in wheezy could also be
affected.


Also considering tiny test with -m32 on amd64:

amd64$ clang -Wall -g -m32 -v -o test test.c

Missing i386-linux-gnu but got x86_64-linux-gnu.
