By trying to build https://github.com/shirou/gopsutil which uses go-sysconf as a dependency I keep getting this error, not sure if it's gopsutil's author mistake or if something is broken over here, just to let you know.

Thanks for the report. Which version of Go are you using on Linux? It seems the version you're using doesn't know about GOARCH=riscv64 yet (i.e. Go 1.10 or earlier).

In any case, I'll add build tags to the generated files which should fix this for older Go versions as well.
