Appears to work for me, at least on SLE12. No idea how much SELinux they
put in there. My old 11.4 behaves the same. Perhaps your kernel lacks
certain functionality? I assome the error msg comes from the kernel.

root@bax:~ # mount -vt tmpfs xxx -o context=foo /mnt/
mount: xxx mounted on /mnt.
root@bax:~ # grep mnt /proc/mounts 
xxx /mnt tmpfs rw,relatime 0 0
