Use Libtool and -R to encode run paths.
* README: Mention the dependencies more clearly near the beginning.
Add a step to use Libtool if it's not already used.
* build-aux/boost.m4 (BOOST_FIND_LIB): Add -R flags in the LDFLAGS
and fix a bug when --with-boost isn't used which leads to
$with_boost being empty which leads that /lib is checked first.
* configure.ac: Invoke AC_PROG_LIBTOOL.
* tests/testsuite.at (AT_CONFIGURE_AC): Import the content of
aclocal.m4 without the m4_include's in order to use AC_PROG_LIBTOOL
without getting the hassle of libtoolize.
(AT_CHECK_MACRO): Do not pass -W obsolete to autoconf to avoid
spurious warnings due to Libtool.
