This is a manual run.  Even with a cross setup, you still run
test-container on the cross target:

$ strace_static -f
~/br/build/glibc-867196a7635/build/support/test-container \
~/br/build/glibc-867196a7635/build/elf/tst-ldconfig-ld_so_conf-update

The containerized tests are (in this case) containerized because they
rely on setup files (like /etc/ld.so.conf) inside the container to run
the test.  Otherwise you end up corrupting the host OS.

The test infrastructure knows how to run containerized tests on remote
machines, though... any reason why you're not using that setup?

Note: if containers aren't yet supported on your platform, it's OK to
just skip those tests.  Also, it's not always a good idea to run a
containerized test outside the container; the tests assume they can
trash the container as part of the test.
