Fix Configure script:

1. move generation of ap_config.h to a later point in the script
   because else it doesn't pick up HIDE or STATUS correctly.

2. change the generation of shared objects from explicit rules to
   implicit rules: First the $< is only portable for implict
   rules (e.g. FreeBSD's make fails) and second we already build
   .o's implicitly, so we should do with .so's the same way.
