Don't use -1 fd and AT_SYMLINK_NOFOLLOW for faccessat()
-1 is not an allowed value for the file descriptor, the only allowed non-file-descriptor value is AT_FDCWD. So use that instead. AT_SYMLINK_NOFOLLOW has a weird semantic: It checks whether we have the specified access on the symbolic link. It also is implemented only by glibc on Linux, so it's inherently non-portable. We should just drop it. Thanks: James Clarke for debugging these issues Reported-by: James Clarke <jrtc27@jrtc27.com> (cherry picked from commit 25f54c960d7a4ceca7bd3e21f87baf48d6cbc2d3)
