+Only move shared libraries to /lib if they exists
+
+In several Makemodule.am, there is a install-exec-hook-<library>
+target whose role is to move the shared library from /usr/lib to /lib,
+while keeping a symbolic link /usr/lib/libuuid.so ->
+../../lib/<library>.so.<version>.
+
+However, when util-linux is built with --enable-static
+--disable-shared (as is needed on noMMU platforms that don't support
+shared libraries), no <library>.so is built, but the
+install-exec-hook-libuuid creates an invalid /usr/lib/<library>.so
+symbolic link, pointing to ../../lib (yes, the directory). This causes
+troubles later one when other libraries/programs are compiled with
+-l<library>, as gcc thinks a shared library is available because
+there's a file named /usr/lib/<library>.so.

Even when compiled with --enable-static --disable-shared, util-linux creates some incorrect libuuid.so, libblkid.so and libmount.so symbolic links, which confuses the compiler which thinks that a shared library is available. This causes some build issues such as: http://autobuild.buildroot.org/results/990/9909d198ce14969d0e9d29a34fcc33f0ef79220d/ This commit fixes that by adding a patch to util-linux that fixes this issue. The patch has been submitted upstream at http://article.gmane.org/gmane.linux.utilities.util-linux-ng/9262.
