I was seeing the same issue on a full kernel compile, which was fixed by
make clean && make

I've started seeing the same error on my PowerPC box, running Gentoo. It seemed specific to that machine, but the GCC version may well be relevant since Gentoo tends to stabilise new GCC versions earlier on minority platforms.
Shouldn't stdarg.h be a built-in header?

Yeah, definitely only shows up in very new GCCs.

Yup, which is why this is really odd...

PPC is running gcc 7.3.0, fails. Haven't tried the workaround yet.
E-450 (amd64) is running gcc 6.4.0, succeeds.
