This is relating to O_TMPFILE not being available with this configuration:

libcontainer/nsenter/cloned_binary.c:206
#ifdef HAVE_MEMFD_CREATE
	memfd = memfd_create(RUNC_MEMFD_COMMENT, MFD_CLOEXEC | MFD_ALLOW_SEALING);
#else
	memfd = open("/tmp", O_TMPFILE | O_EXCL | O_RDWR | O_CLOEXEC, 0711);
#endif

I'm not aware of what the best alternative to O_TMPFILE in this system
setup would be. Do you (or anyone else) know a good solution to patch in
here for compatibility?

Thanks,
Christian

 O_TMPFILE was added in Linux 3.11, memfd some time later IIRC. So depending on
BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_11 seems the correct approach.

Those failures are happening with a toolchain that uses 3.12 kernel
headers.
