RFR: 8348582: Set -fstack-protector when building with clang

[Matthias Baesken]

We noticed -fstack-protector is set when building on Linux with gcc but we miss it in the Hotspot compile calls when building on Linux with clang.
AIX/clang has already the -fstack-protector setting.
MacOS/clang misses it.
