Add RISC-V support for amass

[akifejaz]

Hi

I just confirmed the Amass on native RISC-V machine Milk-V Pioneer Box and as its all go which already supported on RISC-V, I 'had no issue building this for RISC-V. However, I noticed amass do not provide official risc-v release. I would like to propose releasing it for risc-v arch too.

Motivation

• Ecosystem growth: RISC-V adoption is increasing across Linux distributions.
• Build parity: Amass builds cleanly on riscv64 with CGO_ENABLED=0, matching the existing CI defaults.
• Quality signal: A native riscv64 job would ensure ongoing compatibility without relying on emulation.

Proposed scope

• Extend .github/workflows/go.yml with a riscv64 job that:
  • Runs on a self-hosted, linux, riscv64 runner.
  • We can use the RISC-V runner from Cloud-V (official RISC-V Lab Partner) see details here
  • Currently available RISC-V machines on Cloud-V are Banana Pi BPI-F3, Milk-V Pioneer Box, VisionFive 2
• Additive and non-blocking for existing CI.

Next steps

I would like to make this PR, but I’d like to confirm whether the maintainers are interested in including this riscv64 job.

I'm Akif from @10xEngineers working as part of official RISC-V Lab Partner (Cloud-V). I'm mainly working on increasing the SW support for RISC-V and with that intention I'm asking for PR, hoping to provide RISC-V machine for this project so you can also release/test for/on RISC-V.

Thanks!
