Merely changing library options in the src/Makefile.am does not
cause all libraries to be recreated, so it is likely that you are
still using a util library created without -lpthread, and thus
you would not have seen any benefit to my patch.

You can confirm that it is not required by running e.g.,

  touch src/util/util.c && make

without your patch.
