Makefile: introduce NO_PTHREADS
This introduces make variable NO_PTHREADS for platforms that lack the support for pthreads library or people who do not want to use it for whatever reason. When defined, it makes the multi-threaded index preloading into a no-op, and also disables threaded delta searching by pack-objects.
