We want to remove the gcc-multilib package. snapd happens to use it for
testing 32bit seccomp functionality on amd64. An alternative to using
-m32 is to use real cross toolchains. These are more generic than
multilib. I'm attaching a patch that converts snapd to use targeted
cross toolchains for the snap-seccomp test. As a result, it no longer
needs to be skipped. Since the gcc-multilib dependency also is a problem
to cross building, the change improves that aspect as well. Please
consider applying the patch in the forky cycle.
