+Ensure that $(LIBLTDL) is built first
+
+After Automake upstream commit f4e91bfc490d, the list in 'all-am:' is
+reordered for this test-case (*_LTLIBRARIES is before *_PROGRAMS), which
+means that linker will fail to link 'old' binary.
+
+Previously (with automake <= 1.16), it was matter of luck -- it worked if
+(a) the build was serial (-j1), and/or (b) libtool-ltdl-devel package was
+installed on the box so ./configure picked the system version of libltdl.
+
+Users should anyways use system's ltdl, so this has low priority.
