The gold linker is much faster for building static binaries so will be much friendlier for new developers.
I don't think I've seen a problem attributable to gold since it was added ~ 6 months ago. I've been using it since then and we've been using it for some Impala test jobs as well for at least a couple of months. I feel confident that any major problems have been shaken out. Does anyone have any objections? - Tim
