The only thing I can thing of would be that specifying debug= on the
make command line makes it enter the environment or MAKEFLAGS or
something, whereas setting it in the Makefile or .config etc doesn't.
(Perhaps e.g. "export debug" in Config.mk would make these two behave
the same?)

Anyway, that having happened the debug could then filter down and get
picked up by the configure or build system of some sub-component in a
way we aren't expecting.

That's all 100% speculation though.
