+Exclude from the search of bindings any
+directory starting with a dot (.) by default.
+
+It is possible to reactivate the prvious behaviour 
+by defining the following preprocessor variables
+
+ - AFB_API_SO_ACCEPT_DOT_PREFIXED_DIRS
+
+   When this variable is defined, the directories 
+   starting with a dot are searched except
+   if their name is "." or ".." or ".debug"
+
+ - AFB_API_SO_ACCEPT_DOT_DEBUG_DIRS
+
+   When this variable is defined and the variable
+   AFB_API_SO_ACCEPT_DOT_PREFIXED_DIRS is also defined
+   scans any directory not being "." or "..".
+
+The previous behaviour was like difining the 2 variables,
+meaning that only . and .. were excluded from the search.
+
+This change is intended to definitely solve the issue
+SPEC-662. Yocto installed the debugging symbols in the
+subdirectory .debug. For example the binding.so also
+had a .debug/binding.so file attached. Opening that
+debug file made dlopen crashing. 
+See https://sourceware.org/bugzilla/show_bug.cgi?id=22101
