Subject: [PATCH] Fix -O0 build

btb reports that clang fails to link
<https://github.com/dxx-rebirth/dxx-rebirth/commit/77ec36b9c3edf03d43424e3605f59518e4b3a490#commitcomment-9992820>.
When building at -O0, static member glow_num has its address referenced
because the compiler does not inline non-static method
glow_num_stub::operator=.  Add a definition of this symbol.

Fixes: 77ec36b9c3edf03d43424e3605f59518e4b3a490 ("Convert g3_draw_morphing_model to class")
