[Bug 1317307] Re: Make -fstack-protector-strong the default in gcc 4.9

[Steve Beattie]

The attached is an updated version of the testsuite-hardening-
updates.diff patch, which addresses more test failures caused by
enabling -fstack-protector and _FORTIFY_SOURCE by default. The updated
testcases are the following:

+ c-c++-common/cilk-plus/CK/spawnee_inline.c    |    2 +-
+ g++.dg/fstack-protector-strong.C              |    2 +-
+ gcc.c-torture/execute/memset-1.x              |    5 +++++
+ gcc.dg/fstack-protector-strong.c              |    2 +-
+ gcc.target/i386/sw-1.c                        |    2 +-

It includes the added testcase that was included in the patch in comment
#2.
