make the Makefile(s)... mortal-friendly

I did this by making the assumption that the files in a directory are
dividable into 2 groups: those that are executable, and those that aren't, and
that all of the files in each group all go in the same folder when
installed.

These install directories are configurable per source directory with
$(libre_execdir) and $(libre_datadir)
