Fix warning about AM_INIT_AUTOMAKE arguments
As of automake 1.14.2, currently shipped with Ubuntu 14.04, automake
warns about AM_INIT_AUTOMAKE having more than one argument:
configure.ac:41: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see:
configure.ac:41: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
This commit fixes the warnings by following above link's advice, so
AM_INIT gets called with the package's name and version. As both are
defined in the META file we're parsing it with grep, cut and tr.
NOTE: autoconf < 1.14 not supporting m4_esyscmd_s so m4_esyscmd was
used and modified tr to truncate newlines, too.
