+    Enhance _dl_catch_exception to allow disabling exception handling
+    
+    In some cases, it is necessary to introduce noexcept regions
+    where raised dynamic loader exceptions (e.g., from lazy binding)
+    are fatal, despite being nested in a code region with an active
+    exception handler.  This change enhances _dl_catch_exception with
+    to provide such a capability.  The existing function is reused,
+    so that it is not necessary to introduce yet another function with
+    a similar purpose.
