[PATCH] newlib: require automake-1.11.6

This is simply reflecting reality: all the subdirs in here are already
using automake-1.11.6, so making it a requirement will allow us to stop
suggesting we might support automake-1.9 or 1.10 (which I'm fairly sure
do not work today).

This is why only acinclude.m4 changes in this patch: the generated files
are exactly the same as the directives here are automake constraints,
not generated code logic.
