Unfortunately this patch is hard to split up into smaller chunks. Our build system and the associated automake/autoconf/libtool macros has been left untouched for a while, and could use a refresher. * Upgrade ltmain.sh to the latest version * Move away from a huge acinclude.m4 directory to using individual files in the m4/ subdirectory, suggested by upstream automake documentation * Update all macros to their latest available version * Adjust Makefile.am and autogen.sh to accommodate m4/ subdirectory Signed-off-by: Dan McGee <dan@archlinux.org>
