FWIW these issues can sometimes (often?) be fixed by not using =~ at all, 
either by using simple or extended (shopt -s extglob) globbing.  A couple of 
examples from the above:

-    elif [[ "$path" =~ '^\./lib/modules/' ]]; then
+    elif [[ "$path" == ./lib/modules/* ]]; then

-    elif [[ "$file" =~ '^ld-[.0-9]+\.so$' ]]; then
+    elif [[ "$file" == ld-+([.0-9]).so ]]; then

-    elif [[ "$file" =~ '^libbfd-.*\.so$' ]]; then
+    elif [[ "$file" == libbfd-*.so ]]; then
