The nss source package is getting a build failure on x32:

It should be using -mx32 instead of -m32.  I'm attaching a debdiff for
changes I applied to get the package to build on x32, for an upload to
debian-ports/unreleased.  (It's very loosely based on the patch from
Gentoo, except I made it based on an amd64 build where they made it
based on an i386 build.)
