This is a bug in the way MAKEDEV uses pax. It works the first time, but
complains about already existing files on subsequent runs.
I have some almost completed work in progress to allow MAKEDEV to use
mtree instead of pax for creating device nodes in bulk. I expect to
commit it within a day.

It's definitely a bug, but I though it was harmless. If devices have
changed to symlinks then obviously it's not harmless.
Here are some workarounds:
# fast, uses mtree
MAKEDEV -s all | mtree -u -e
# slow, uses "mknod -r"
MAKEDEV -m mknod all
# slow, uses "mknod -R"
MAKEDEV -f all

I don't think there's a PR. Raise one if you like, or just wait until
I commit my fix to use mtree in preference to pax.
