Bug#1079736: libgdk-pixbuf-2.0-0: "Exec format error" in foreign-arch installation

[Daniel Richard G.]

Package: libgdk-pixbuf-2.0-0
Version: 2.42.12+dfsg-1

I am installing this package as a cross-compilation dependency for an
amd64-to-armhf build. In the install log, I see

    Setting up libgdk-pixbuf-2.0-0:armhf (2.42.12+dfsg-1) ...
    /var/lib/dpkg/info/libgdk-pixbuf-2.0-0:armhf.postinst: 30: /usr/lib/arm-linux-gnueabihf/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders: Exec format error

The postinst script should check that the package is being installed on
a compatible architecture before running this (binary) program.
