Allow to build 10.6 binaries on Darwin x86_64 (the following binaries were actually built on such).
Roll the newer (r4383) TSan binaries for Mac OS 10.6 which reports less errors than the previous one (r2939) locally.
Because we didn't track the TSan versions before, I've set them to unknown for all the platforms.
