I already got answer from the libtool list and it's just as I thought.
Using version-script limits the portability to GNU ld and solaris and
libtool offers no other options.

Do you mean to always do symbol renaming and additionally use
--version-script if supported? I think this is the best solution and I
made the necessary changes so the configure script checks whether the
linker support the version-script argument.

I implemented the symbol renaming by adding a single file to all 3
libraries which redefines all external symbols. The changes to the other
files are minimal so updating any of the libraries shouldn't be a big
problem.

I will test the code again on the systems I have access to and will
finally commit the changes if everything works as expected.
