- this creates a set of static html-meta-redirect-pages linking the UNO
  implementation name to its C++ class, while doing a clang compile from
  scratch
- the output is written to $(WORKDIR)/ServiceImplementations
- still quite some corner cases missing, e.g:
  - anonymous namespaces
  - non-trivial getImplementationName() functions
