Currently, we can build a static-only zlib, but not a shared-only one. This is because zlib's build-system is a custom ./configure (not using autotools), and does not allow building/installing only the shared library. Simply remove the .a as a post-staging install hook. We don't care removing it from target, since it is not used at link time to build other packages, and it is anyway removed later before assembling the filesystem images anyway.
