* stuff is in the wrong directory, move to sbin
* CFLAGS is abused for preprocessor, move to CPPFLAGS
* add missing $(LIBGTPNL_CFLAGS)
* ggsn includes libmnl.h but fails to PKG_CHECK for it;
  turns out it only uses the header and no defs, so kill that.
* _DEPENDENCIES on files not generated by $this Makefile are pointless
* must use .la files in _LDADD/_LIBADD whenever they exist
* remove AC_PROG_CXX, the C++ is never used
