It is normal, given that some people wants to keep multilib enabled,
even with multiarch. The i386 version is in
/usr/include/i386-linux-gnu/{bits,gnu,sys}/*.h .

Normal again, the files in /usr/include/i386-linux-gnu/ are i386 only
and can't be used for x86-64. See bug #637000.

stubs-32.h is only there because it's an i386 only header. The problem
is that your compiler is not multiarch aware. Everything is correct in
the package side.
It's basically the same bug than #629819 (crti.o, crt1.o), but for the
headers. The same workaround, explained in NEWS.Debian.gz applies. I am
therefore merging the bugs.
