So another theory goes up in smoke :(

Well, almost. What you have listed there as CPPFLAGS should actually
be CFLAGS. CPPFLAGS, although seemlingly for C++ processing,
actually stands for CPreProcessorFLAGS. With that change, yes,
-mthumb tells the compiler to generate Thumb code and -mthumb-interwork
tells it to make it able to call, and be called by, ARM code. You also need
-mthumb-interwork (by itself) when compiling ARM code if you expect to
link with Thumb code.
