AutoGen: Don't iterate over a container while populating it. 

The InitializeAutogenTarget creates new targets and adds them to the
Targets container on the makefile.  In this method, we have a reference
to that container and we are iterating over it.  That happens to work
with hash_map, but it fails with undefined behavior when using the
std::unordered_map from libstdc++-4.9 (and likely others).
