I think here you are referring to an *import* library, or what dlltool
seems to call and *interface* library.  You certainly can't create a
static library from an existing dynamic libray, but you can create an
import library from a dynamic library.  Check the documentation of
dlltool, which can create the .lib file from a .def file.  Or just use
-Wl,--out-implib when building the DLL and you will get an import
library (.a) for it, which you can just rename to .lib.  If all you have
is the dll you can use 'pexports' to create a .def file and then dlltool
to create the import library.  You may even be able to do this in one
step with dlltool, I'm not sure.
