f430b04f332d6b89cb8447b07217e391e1c38000 by Derek Mauro <dmauro@google.com>:

Migrate the Linux CMake tests from GCC 4.8 to the GCC latest
version. This will allow us to delete the GCC 4.8 test since that is
currently our only CMake coverage. This also means that we don't have
to update the script every time we move to a new minumum GCC version.

This change includes a fix for a -Wstringops-truncation warning in
symbolize_test.cc that triggers when it is built in release mode with
the latest GCC.
