For the WASM one (disclaimer: I built it) it's at least reasonably simple to reproduce the build [1], and the resulting blob is fully cross platform.
Also, although I do (lightly) patch SQLite which might invalidate results in your view, the SQLite team is producing/testing/releasing WASM builds of SQLite built with much the same toolchain, which, hopefully, smokes out compiler bugs.
Which one do you mean? The WASM one? It includes WASM, it needs to be compiled too.
Ah github.com/cvilsmeier/sqinn-go. Which... is made by the same person that made this benchmark...?
edit: and that requires some random binary to be pre-installed...? Which is in C anyway?

so I don't see any "actually written in go".
