Why do you want to do this? [When shared libraries exist - the
compiler prefers then - instead of static. So you should just stick
with the compiler default behavior. And if build PETSc with
--with-dynamic - then the .a files are useless anyway.]

So the shared vs static usage should be chosen at PETSc configure step.
[--with-shared=1/0, and do not use --with-dyanmic] 

So  you should just use:

-lpetsccontrib -lpetscts -lpetscsnes -lpetscksp -lpetscdm
-lpetscmat -lpetscvec -lpetsc
