#6 Build failed. Outdated config.guess and config.sub file in the latest release of scponly.

[Yuluo]

I am trying to build scponly for a linux distro on riscv64 architecture.
Using the latest release, got a build error, configure: error: cannot guess build type; you must specify one.
It was caused by outdated config.guess and config.sub file in the latest release.
