> For a solo dev, what are the advantages of _not_ building on your own machine?

I end up with all kinds of random crap on my own machine. It's very easy to accidentally e.g. globally install a library that wasn't properly listed in my dependency management. So having a separate standardised/controlled build environment is a good way to catch those. It also helps with flaky tests or random "works on my machine" problems - this way my tests are at least getting run on two quite different machines (different OS/arch/etc.)
