As far as I understand ELF shared objects, it is not recommended to link 
a static library into a dynamic plugin (i.e. an ELF shared object), 
because the static library is not compiled with -fPIC.
(if you do that, the resulting plugin is getting a huge lot of 
relocation information).
In simpler words, *.so have to be compiled with -fPIC, and libiberty is 
not compiled with -fPIC.

I am clear enough or should I explain more?

Regards.
