Make sure .pc, .prl and .la files are created for header_only modules

Those modules are TEMPLATE=aux, so they weren't triggering the file creation
here.

To make this work properly we have to:
  - check for TEMPLATE aux in the right places
  - add a dummy target to INSTALLS to actually trigger the creation
  - initialize PRL_TARGET for aux templates
