You want DEB_HOST_MULTIARCH, not DEB_BUILD_MULTIARCH, for this. When
cross-compiling, DEB_BUILD_MULTIARCH is the machine on which the package
is being built, which is only rarely an important piece of information.
(For example if you cross-compile a package for mipsel on amd64, the host
architecture is mipsel and the build architecture is amd64. The multiarch
tuple my script would need from the postinst is the one for mipsel.)
If in doubt, the _HOST_ variables are usually the right ones to look at.
