If all target libraries are assumed to be built with libtool, then we 
can indeed defer to the user.  If not, then we have to do something; the 
user has no way to control the fact that some target libraries need 
libtoolification of their options, while others do not.

I do understand what you mean about quoting and about reusable scripts. 
  I suppose I could work on that, once we know what we want it to do.
