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

Well... fchmodat is a different function and you might expect it
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. ;-)
