-fstack-check compilation flag causes binary incompatibility for container-executor between RHEL 6 and RHEL 7

The segmentation fault in container-executor reported in YARN-7796 appears to be due to a binary compatibility issue with the -fstack-check flag that was added in YARN-6721

Based on my testing, a container-executor (without the patch from YARN-7796) compiled on RHEL 6 with the -fstack-check flag always hits this segmentation fault when run on RHEL 7. But if you compile without this flag, the container-executor runs on RHEL 7 with no problems. I also verified this with a simple program that just does the copy_file.

I think we need to either remove this flag, or find a suitable alternative.
