Subject: [PATCH] Add CONFIG_NO_WORKER Makefile option

This option eliminates the dependency on the pthread library. This mode is
already toggled on _WIN32 and/or EMSCRIPTEN is detected, here we just allow the
user to toggle it at will at the top level.

This slightly reduce the code size as well, and may allow compiling this
library in some embedded contexts where pthread is not available or is broken.
