I can do that, but I'm not sure which one to set; running
'tlmgr platform list' on my machine, I have

(i) universal-darwin
[…]
(i) x86_64-darwin

Of the two, which would be best?

Not a portable way. Using sysctl might give what you're looking for
on Darwin, and is probably more specific than uname (which I'd assume
isn't working on OS X if config.guess is using the C compiler). As
example:

$ sysctl -a |grep [xX]86
kern.version = Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64
hw.machine = x86_64
kern.version: Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64
hw.optional.x86_64: 1

I've no idea what the output is on PPC systems or previous versions,
though we could figure it out.
