autotools: Silence warnings from autoreconf

Previously invoking ./bootstrap.sh would output:

         $ ./bootstrap.sh
         + AUTOCONF_FILES=Makefile.in aclocal.m4 ar-lib autom4te.cache compile
         config.guess config.h.in config.sub configure depcomp install-sh
         ltmain.sh missing *libtoo
         l test-driver
         + autoreconf -i
         libtoolize: putting auxiliary files in '.'.
         libtoolize: copying file './ltmain.sh'
         libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
         libtoolize: and rerunning libtoolize and aclocal.
         libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
         configure.ac:22: installing './compile'
         configure.ac:22: installing './config.guess'
         configure.ac:22: installing './config.sub'
         configure.ac:5: installing './install-sh'
         configure.ac:5: installing './missing'
         Makefile.am: installing './depcomp'
         parallel-tests: installing './test-driver'
         + echo Run "./configure ${CONFIGURE_FLAGS} && make"
         Run "./configure ${CONFIGURE_FLAGS} && make"

Address the three lines:

         libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
         libtoolize: and rerunning libtoolize and aclocal.
         libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
