What does this have to do with fink?
Fink just wants things to Work(tm), and our maintainers able to cope
with whatever packages do. We don't write libtool, we don't patch
libtool locally, we don't have fink-specific behavior. Fink is just a
perl-script that calls system("./configure --prefix=/sw && make") and
such. As idiosyncratic as libtool can be, it's easy to use it and get
something that works as long as the author of the package fink is
compiling actually uses libtool per its manual and doesn't subvert its
magic. If those authors are not using things "correctly for whatever
libtool they are distributing", that's their bug; fink folks just
whine about "they are distributing something broken" and hack around
it without really distinguishing blame to libtool vs the author who is
mis-using libtool.
