Log: Only enable -fstack-protector-strong on gcc 4.9+ and default to -fstack-protector when -fstack-protector-strong is not available, like it was implicitly before r288669 As noted by antoine@, devel/gcc (which is 4.8.5) lacks -fstack-protector-strong support, whereas 4.8.4i (devel/gcc48) has the support. Until a version is available which has -fstack-protector-strong support, be conservative and only enable support with 4.9+.
