Hm.  So, these oversights are certainly bugs in narrow terms.  However,
they've all been like that for a *long* time --- the three instances
you found date to 2005, 2006, and 2008 according to "git blame".
The complete lack of complaints shows that nobody cares.  So I think
a fairly strong case could be made for going the other way, ie
s/$(LN_S)/ln -s/g and get rid of the configure-time cycles wasted in
setting up that variable.
