Well, that is simple enough to find out..

        git show 77433830ed164

just tells us.

Of course, that also points to scripts/Makefile.lib, which doesn't
have this problem, because it keeps c_flags and a_flags nicely
separated.

Anyway, that just makes me think that something like that patch in my
previous email is the way to go, but I would like to stress (again)
how little testing it had: exactly none.

So please consider that nothing more than a hand-wavy "something like this".
