One thing could be always returning 0, as this is really a no-op on
Linux.

Well... fchmodat is a different function and you might expect it
failing.
But since a platform _is_ providing lchmod one should not expect it to
return not-supported when used on a symlink.
It would give me a serious WTF reading a code that uses a platform
supported function and checking for not-supported error. ;-)

Is it a documented result for lchmod? (Google is no help here.)
(If yes, I will die a little and just move on ;-)
