You're right: it does look like cmd/link imposes a 2G total limit. This is not a limitation of the 64-bit ELF format. It should be possible to make it larger. Note that such files are going to take a long time to create and will be unwieldy to use. While it should be possible to increase the size, I would not be surprised if you hit other limits fairly quickly.
