Merge branch 'jc/make-libpath-template'

The Makefile often had to say "-L$(path) -R$(path)" that repeats
the path to the same library directory for link time and runtime.
A Makefile template is used to reduce such repetition.

* jc/make-libpath-template:
  Makefile: simplify output of the libpath_template
  Makefile: reduce repetitive library paths
