TensorFlow failing on Bazel CI with Ubuntu 14.04

Error message:

external/com_github_googlecloudplatform_google_cloud_cpp/google/cloud/bigtable/internal/rowreaderiterator.h:57:44: error: ambiguous overload for 'operator*' (operand type is 'std::remove_reference<const google::cloud::v0::internal::optional<google::cloud::bigtable::v0::Row>&>::type {aka const google::cloud::v0::internal::optional<google::cloud::bigtable::v0::Row>}')

Because it's only failing on 14.04, I suspect it's caused by compiling with an old gcc version.

culprit: 2e764644d6

Do we care about building TF on Ubuntu 14.04? If so we might need to fix code from https://github.com/GoogleCloudPlatform/google-cloud-cpp

+1. I meet the same problem in CentOS 7. Any help?

@jiangcore
i comment out line 126,127,128 in external/com_github_googlecloudplatform_google_cloud_cpp/google/cloud/internal/optional.h
and line 57 in external/com_github_googlecloudplatform_google_cloud_cpp/google/cloud/bigtable/internal/rowreaderiterator.h
it works!

This issue is better submitted to Google Cloud Platform issues since it is not a TensorFlow bug or feature request.

@tommiebupt I am experiencing the same problem with TF 1.12 and compiling with GCC 4.9
Where are the files to edit? The only ones I could find are under the folder "bazel-tensorflow", but I cannot modify those without creating a problem with the cache of bazel.

Moreover, there is a comment on line # 59 of rowreaderiterator.h, which says that line # 60 should be commented out with GCC 4.8. Should be the same with 4.9? Maybe this is the reason.

There is a way to exclude Google cloud from the beginning? Thanks a lot in advance, and sorry for so many questions.
