    Add -fno-strict-aliasing workaround for all GCC targets
    
    Use a GCC option to work around aliasing bugs. See commit 013dbcd for
    more details.

    configs: Set -fexceptions for GLUT on linux-dri like other targets
    
    Quite a while ago, the GCC option -fexceptions was added for building
    libglut. See here:
    
      http://article.gmane.org/gmane.comp.video.mesa3d.devel/9499
    
    This was missing in the linux-dri targets.

    configs: Always use -fPIC for shared libraries, never for static
    
    Mesa currently disables -fPIC for DRI on x86, but most Linux distros are
    re-enabling -fPIC for all DRI arches. Let's just do that here since
    that's normally what's wanted for shared libraries. Some justification:
    
    http://bugs.gentoo.org/show_bug.cgi?id=110840#c9
    
    On the other hand, position-independent code is only necessary when
    building shared libraries, so disable it for the static cases.

    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)
