commit 9fb936abdce72e313e77aa15f0b9fc95c7fea512
Author: Chun-Hung Hsiao <chhs...@mesosphere.io>

Fixed gRPC compilation with Clang when building Mesos.
When compiling gRPC with Clang, there are some array-out-of-bound
warnings due to the use of GLIBC's `__strcmp_cg` macro in the c-ares
library. With `-Werror` on, these warnings would stop gRPC from
compiling. This patch ignores such errors.
