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.
(cherry picked from commit 013dbcd6111bc880e65ed00a7ca31e19230a81d5)
