What is libbfd.la good for? It has

dependency_libs=' 
-L/export/build/gnu/binutils-import/build-i686-linux/libiberty/pic -liberty'

See about. I simply don't like the idea of dependency on static

I don't need libtool to add things which don't belong there. libtool
should just behave like ld/ar and nothing more.
