This one looks better to me, except that I would really make this
an explicit #ifdef __linux__.  The lack of a proper ENOATTR is
a Linux specific quirck and not related to the presence of
non-standard ENODATA.  Maybe also add a little comment why
we're doing this so people don't get confused by it.

Btw, how does libattr actually work for you on FreeBSD?  Last time
I checked FreeBSD had slightly different xattr system calls that (just
like IRIX) used an integer namespace value instead of the string prefix
in Linux.
