merge revision(s) a19228f8: [Backport #16979]

	brace the fact that lchmod(2) can EOPNOTSUPP

	Musl libc has this function as a tiny wrapper of fchmodat(3posix).  On
	the other hand Linux kernel does not support changing modes of a symlink.
	The operation always fails with EOPNOTSUPP.  This fchmodat behaviour is
	defined in POSIX.  We have to take care of such exceptions.
