The SCons build using GCC on Mac OS X is failing now. The SCons build with
clang on Mac OS X completes though.

    _mesa_meta_GenerateMipmap: Support all texture targets by generating
shaders at runtime

    glsl path of _mesa_meta_GenerateMipmap() function would require different
fragment
    shaders depending on the texture target. This patch adds the code to
generate
    appropriate fragment shader programs at run time.
    Fixes https://bugs.freedesktop.org/show_bug.cgi?id=54296

    V2: Removed the code for integer textures as ARB is planning to
        disallow automatic mipmap generation for integer textures.
        Now using ralloc_asprintf in setup_glsl_generate_mipmap().

    NOTE: This is a candidate for stable branches.
