Nice! On my i386 natty machine, this is the pattern:
/lib/i386-linux-gnu/libnss_*so*

I think the architecture independent fix would include a call to
dpkg-architecture. dpkg-architecture returns this on my Ubuntu natty
system:

DEB_BUILD_ARCH=i386
DEB_BUILD_ARCH_OS=linux
DEB_BUILD_ARCH_CPU=i386
DEB_BUILD_ARCH_BITS=32
DEB_BUILD_ARCH_ENDIAN=little
DEB_BUILD_GNU_CPU=i686
DEB_BUILD_GNU_SYSTEM=linux-gnu
DEB_BUILD_GNU_TYPE=i686-linux-gnu
DEB_BUILD_MULTIARCH=i386-linux-gnu
DEB_HOST_ARCH=i386
DEB_HOST_ARCH_OS=linux
DEB_HOST_ARCH_CPU=i386
DEB_HOST_ARCH_BITS=32
DEB_HOST_ARCH_ENDIAN=little
DEB_HOST_GNU_CPU=i686
DEB_HOST_GNU_SYSTEM=linux-gnu
DEB_HOST_GNU_TYPE=i686-linux-gnu
DEB_HOST_MULTIARCH=i386-linux-gnu

So DEB_HOST_MULTIARCH would be correct. But my Debian squeeze x86_64
system doesn't have MULTIARCH variables, this is its output:

DEB_BUILD_ARCH=amd64
DEB_BUILD_ARCH_OS=linux
DEB_BUILD_ARCH_CPU=amd64
DEB_BUILD_ARCH_BITS=64
DEB_BUILD_ARCH_ENDIAN=little
DEB_BUILD_GNU_CPU=x86_64
DEB_BUILD_GNU_SYSTEM=linux-gnu
DEB_BUILD_GNU_TYPE=x86_64-linux-gnu
DEB_HOST_ARCH=amd64
DEB_HOST_ARCH_OS=linux
DEB_HOST_ARCH_CPU=amd64
DEB_HOST_ARCH_BITS=64
DEB_HOST_ARCH_ENDIAN=little
DEB_HOST_GNU_CPU=x86_64
DEB_HOST_GNU_SYSTEM=linux-gnu
DEB_HOST_GNU_TYPE=x86_64-linux-gnu

I guess this change will have to go into the Debian package too, since
Debian will have multiarch support eventually:
