I am already past that point in my build.  auto-host.h is an automatically
generated file, so I am quite puzzled why in your case it has not found it.  In
my case, it is in obj/gcc/auto-host.h.  I built with your parameters.

Was this a new build from a new checkout? If you updated from an existing src
base, did you run make distclean over the old build?  Or just start with a new
obj/ location?
