+configure: set macro directory
+
+Setting the macro directory in configure.in, rather than specifying it
+on the command line, ensures that it is properly searched in the correct
+order, and that autoreconf properly updates our macros with the newer
+system ones, if any.
+
+Fixes:
+ http://autobuild.buildroot.org/results/63a/63ae0bddb3c4436efe967c318e299047f496c5a5/build-end.log
+
+ libtool: Version mismatch error. This is libtool 2.4.6, but the
+ libtool: definition of this LT_INIT comes from libtool 2.2.6.
+ libtool: You should recreate aclocal.m4 with macros from libtool 2.4.6
+ libtool: and run autoconf again.
