Use both AC_CONFIG_MACRO_DIR and ACLOCAL_AMFLAGS

libtoolize(1) tool suggests adding AC_CONFIG_MACRO_DIR macro to
configure.ac, and gtkdocize tool also uses AC_CONFIG_MACRO_DIR from
configure.ac to find out where to install gtk-doc.m4 file.

According to libtool documentation at
http://www.gnu.org/software/libtool/manual/html_node/Invoking-libtoolize.html

"If libtoolize detects an explicit call to AC_CONFIG_MACRO_DIR (see The
Autoconf Manual) in your configure.ac, it will put the Libtool macros in
the specified directory.

In the future other Autotools will automatically check the contents of
AC_CONFIG_MACRO_DIR, but at the moment it is more portable to add the
macro directory to ACLOCAL_AMFLAGS in Makefile.am, which is where the
tools currently look.  If libtoolize doesn't see AC_CONFIG_MACRO_DIR, it
too will honour the first ‘-I’ argument in ACLOCAL_AMFLAGS when choosing
a directory to store libtool configuration macros in.  It is perfectly
sensible to use both AC_CONFIG_MACRO_DIR and ACLOCAL_AMFLAGS, as long as
they are kept in synchronisation."
