[Toybox] [PATCH] ln: add -T, use FLAG()

[Ryan Prichard]

It looks like coreutils and busybox allow only 2 args with -T. Do we need
to diagnose this?

touch A B
ln -sfT A B L
ln: extra operand 'L'

busybox ln -sfT A B L
ln: -T accepts 2 args max

toybox ln -sfT A B L
ls -l L
lrwxrwxrwx 1 rprichard primarygroup 1 Sep 25 13:38 L -> B

With this patch, ln is overwriting the symlink twice, leaving it pointing
at B.
