Although sys/errno.h defines different values for ENOTSUP and
EOPNOTSUPP (same as hppa-linux values), I have not seen this problem
on HP-UX 10 or 11.  It looks like getfilecon is selinux specific.
On HP-UX, getacl() returns EOPNOTSUPP if the operation is not
supported on the file system.  I would guess it does this consistently.

It would seem that getfilecon() returns the wrong error code, or
the manpage is wrong.  I see that getfilecon_raw() can return 
EOPNOTSUPP:

        if (ret == 0) {
                /* Re-map empty attribute values to errors. */
                errno = EOPNOTSUPP;
                ret = -1;
        }

getfilecon_raw() uses getxattr().  The manpage for getxattr()
says it returns ENOTSUP if extended attributes are not supported.
This is a syscall and it will take a bit more digging to see if
it is consistent with the documentation.
