TBB for OSX: 32 or 64?
When I look at the OSX build scripts I see we're building Firefox with x86_64 architecture, while everything else, including the bundle is i386.
All the macs (<5-6yrs old) are 64bit. Older macs are awefuly out-dated, and even if we're trying to support them, [it seems to me that] we're doing it wrong. I believe we should either upgrade all the gitian build scripts to x86_64 OR support both architectures properly.
