bpo-36146: Add TEST_EXTENSIONS to setup.py (GH-12129)
Add TEST_EXTENSIONS constant to setup.py to allow to not build test extensions like _testcapi. Changes: * Add add_ldflags_cppflags() subfunction * Rename add_compiler_directories() to configure_compiler(). * Remove unused COMPILED_WITH_PYDEBUG constant. * Use self.add() rather than accessing directly self.extensions. * Remove module_enabled() function: check differently if curses extension is built or not.
