+Subject: [PATCH] make: set plugin SONAME to the installed filename
+
+The plugins are linked with SONAME lib$(PLUGIN_NAME).so, but they are
+installed as $(PLUGIN_NAME).so.$(PLUGIN_VER) and loaded via dlopen()
+using that filename. A library whose SONAME does not match any
+installed filename confuses tooling which verifies that a symlink
+named after the SONAME exists, for example the OpenWrt CI runtime
+tests:
+
+    Library /usr/lib/olsrd_arprefresh.so.0.1 has SONAME
+    'libolsrd_arprefresh.so' but no corresponding symlink was found
+
+Use the full installed filename as SONAME instead. This has no
+functional effect on olsrd itself, since the plugins are dlopen()ed
+by path and never linked against.
