Build artifacts for riscv64

[ffgan]

hi there.

Recently, riscv64 has gained widespread adoption, and we might consider adding riscv64 support to jd. Go has excellent support for riscv64, so we only need minor modifications to enable building artifacts for riscv64.

I ran make build on an riscv64 server, and the results show everything went smoothly.

See details here, build.log

I noticed that I should run make fuzz, but found that the results don't seem quite ideal. I also ran it on my x86 machine, but encountered errors as well. However, the x86 run in CI didn't report any errors, which is somewhat puzzling to me.

See specific logs below

name	URL
x86-local	x86.log
riscv64-local	riscv64.log
x86-ci	CI

Nevertheless, I believe this should be unrelated to riscv64 and should also be unrelated to this PR, so I've deliberately ignored handling this error here.

So, if you have any questions about the above content, feel free to @ me directly anytime. I'm happy to answer all questions.
