Log Message:
Make squeak build again:
- correctly override the libtool used by the build.
- patch-ao: rearrange linker arguments so that vm/vm.a pulls in the libraries.
- patch-ap: fix building of npsqueak browser plugin (use cc as compiler. add
  .so suffix to plugin)
- for whatever reason the plugins are now installed with .a and .so suffixes.
  adjust PLISTs accordingly.

I can now at least start the vm again.
