In Snow Leopard "platform.machine()" returns "i386" while
"platform.architecture()" returns ('64bit',''). Using information from both
we can determine the proper architecture
This reverts commit ea29e137b5 re-enabling the
64bit build on Macintosh.
I don't have access to this OS to fix the issue properly, so for the moment
I'm reverting back to 32bit build on Darwin. We changed to native 64bit in
8ddf930901.
Thanks to Johan Dahlberg and Tim Caswell for reporting and debugging this.
Had to add some waf hackery to override V8's architecture choice. They
probably have a reason for defaulting still to IA32, but all tests are
passing for me, and it makes it easier on users-and I think chrome is using
x64 builds too. So let's go for it!
