Subject: [PATCH v6 16/22] dyndbg-test: build it with just CONFIG_DYNAMIC_DEBUG_CORE

Make the test-module buildable with just CONFIG_DYNAMIC_DEBUG_CORE;
add CFLAGS_$ofile defns to supply -DDYNAMIC_DEBUG_MODULE to cc.
Change the Kconfig entry to allow building with just _CORE, and fix
the help text.
