Add defs for makefile installation dir vars

Browse Source 
Add macro definitions to AM_CPPFLAGS to propagate makefile installation
directory variables for libexecdir, runstatedir, sbindir, and
sysconfdir.

https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Installation-Directory-Variables.html

  A corollary is that you should not use these variables except
  in makefiles. For instance, instead of trying to evaluate
  datadir in configure and hard-coding it in makefiles using e.g.,
  'AC_DEFINE_UNQUOTED([DATADIR], ["$datadir"], [Data directory.])',
  you should add -DDATADIR='$(datadir)' to your makefile's definition
  of CPPFLAGS (AM_CPPFLAGS if you are also using Automake).

The runstatedir directory is for "installing data files which the
programs modify while they run, that pertain to one specific machine,
and which need not persist longer than the execution of the program".

https://www.gnu.org/prep/standards/html_node/Directory-Variables.html

It will be defined by autoconf 2.70 or later, and default to
"$(localstatedir)/run".
