It seems it's both script & webkit that need atomics.
However i think the arch supports list is flawed as well, webkit hasn't 
worked for many of those architectures in the past - they build, yes, 
but they'll probably crash on startup.
But i'm not about to test all of them since that would require hardware, 
so i'm removing sparc as well since it's a cliche that can't be fixed.
Regards.
