buildsys: cleanup libtool and autoconf initialization

Browse Source 
- Use LT_INIT over AC_PROG_LIBTOOL, as the latter is a deprecated alias
  for the former.
- Remove redundant macros which are called implicitly by LT_INIT.
- Remove unneeded AC_PROG_CXX call (we don't use c++ anywhere)
- Add AC_CONFIG_MACRO_DIR([m4]) -- not strictly necessary, but added for
  consistency with autogen.sh and Makefile.am
