Where is stdarg.h expected to come from if not from stdinc (i.e.
-nostdinc).  I don't believe there is one in kernel distribution.

I just had this problem and I'm embarassed to say I'm not quite sure
what caused it. I was building on a ppc64 box, but when I switched from
the ppc32 "cross-compiler" to the native toolchain (which is ppc32) the
problem went away.

Your cross-compiler includes this file in
<prefix>/lib/gcc-lib/powerpc-linux/<version>/include/ .
