+    Fix nut-scanner compilation in some environments
+    
+    Following the commits 5187dab (common: add some string-related functions) and
+    e767df5 (common: consolidate some string-related functions), the build rules of
+    nut-scanner were not updated to also use str.c. Since the libcommon.la
+    dependency was still there, some environments managed to build cleanly, while
+    other are failing.  Update build dependencies to fix this situation
