Add -fno-strict-aliasing workaround for Linux GCC targets
Most Linux distros work around aliasing problems in Mesa by compiling with the GCC option -fno-strict-aliasing. Two examples: https://bugs.freedesktop.org/show_bug.cgi?id=6046 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=394311 This makes -fno-strict-aliasing the default with a comment that developers should consider commenting it out. There is a already a note about these bugs in docs/helpwanted.html.
