libiberty isn't built as a shared library (at least not, when specifying
--enable-shared). I had a look at some makefiles in gcc and it seems to
me that multilibs aren't the right thing to build static and shared
library-versions. I have the impression (I don't fully understand the
gcc makefiles) that shared compilation needs to be supported 'by-hand'
in the appropriate Makefile.in's.

libstdc++ is the only library which is also build shared on my system,
so it seems I'll need to have a look at this.
