IMHO it would be good the check whether the problem is just with a dead
variable, or is there a real functional issue with the shader.

(If other drivers have accepted latter, they're pretty broken too...)

If env vars work with Android, you can do that either by using my original
patch:
https://bugs.freedesktop.org/attachment.cgi?id=126582

Otherwise you could add the check from it to Kenneth's:
   if ((existing->data.used && var->data.used) 
   -> still error
   else
   -> warning

Or dump & inspect the shader code directly.
