rustc situation and support for older Macs

[Riccardo Mottola]

Hi,

what is the situation of Rust on our various systems and architectures?

I know that with PPC we are out of luck right? Would be potentially cool.
And i386 vs amd64?

What about e.e. 10.9, 10.11 of which apparently upstream removed 
support? are we able to build it anyway, patch the backports of something?

Discussion came with SeaMonkey people which still support right now 
10.11 (there was discussion about 10.9, but nobody stepped in... they 
didn't ask me!) but there are outstanding patches that can't be merged 
because they require 1.78
