Probably doesn't. Ralf has done lots of work on libtool HEAD, making it 20% faster, but that will not be in a libtool release anytime soon.
Part of the problem here is the use of a convenienve library to hold several thousand object files and then making a shared library with the convenience library. On many platforms, those without a --whole-archive flag, libtool will extract the convenience archive all over again. Linking the shared library all in one go would be faster.
