* Basically we want libGL to be loaded second, after librenderdoc. This is
in order to make sure dlsym(RTLD_NEXT) can work.
* This can be done just by order in the ld command. Unfortunately since
renderdoccmd links directly against librenderdoc (rather than LD_PRELOAD)
any symbols exported by librenderdoc resolve, so unless we reference a
function that isn't exported by librenderdoc, libGL won't be linked in
at all.
* I realise this is probably a horrible hack, but it works for now.
