libgtk-3-bin is not an M-A:same package, so it shouldn't be qualified, 
this seems to be a dpkg problem:

$ dpkg-query  --show -f='${binary:Package}\n' libgtk-3-bin
libgtk-3-bin
$ dpkg-query --admindir=/tmp/piupartss/tmpiAokhZ/var/lib/dpkg --show -f='${binary:Package}\n' libgtk-3-bin
libgtk-3-bin:i386
$ sudo chroot /tmp/piupartss/tmpiAokhZ dpkg-query  --show -f='${binary:Package}\n' libgtk-3-bin
libgtk-3-bin

ok, adding amd64 as a foreign architecture and installing hello:amd64 in the chroot:

$ sudo chroot /tmp/piupartss/tmpiAokhZ dpkg-query  --show -f='${binary:Package}\n' hello
hello:amd64
$ dpkg-query --admindir=/tmp/piupartss/tmpiAokhZ/var/lib/dpkg --show -f='${binary:Package}\n' hello
hello

I would expect the output from dpkg to be consistent from inside and 
outside the chroot.

which is a regression from jessie :-( (since I recently updated my host to stretch)
(jessie is maybe not correct w.r.t. the foreign hello package):

$ /tmp/pbuilder/build/8258/usr/bin/dpkg-query  --version
Debian dpkg-query package management program query tool version 1.17.25 (amd64).

$ /tmp/pbuilder/build/8258/usr/bin/dpkg-query --admindir=/tmp/piupartss/tmpiAokhZ/var/lib/dpkg --show -f='${binary:Package}\n' libgtk-3-bin hello libc6
hello
libc6:amd64
libc6:i386
libgtk-3-bin
