Those kernel config parameters are currently designated "optional" in
the systemd README file, and I'd be really annoyed to find out they
aren't.  I have no use for the extended attribute and ACL support in a
non-SELINUX context, but it would not surprise me in the least to find
out that systemd has some kind of dependency on it.  I'll enable those
options for my next build.

Worth a try.
