Yes, of course AutoReqProv: off turns off all dependence generation.
glibc is also missing but of course it's unlikely you'd miss that ;)

With AutoReqProv enabled the build succeeds (guess that's an improvement
from 10 years ago!), and the result looks good as well.  There's no
shared libraries built for cross-arm-none so this might be a bit misleading
as that target builds with --disable-shared.

I'll try what happens with a "real" cross.
