Additional context
Only ARM, x86 and x64 are currently accounted for in linux.rs and getcontext.rs, causing failure to compile in Risc-V:

Originally reported in EmbarkStudios/crash-handling#100, but that's only because crash-context is a dependency of this crate. I don't know what plans Firefox has to support RISC-V if any, so putting this issue here instead since even if I (I have no personal motivation to do any work on it) or someone implements getcontext for RISC-V, this crate would still need to do further work.

Thanks @Jake-Shadle. For anybody stumbling upon this, RISC-V is not even a tier-3 platform for Firefox, so we won't be able to work on it anytime soon. Patches are welcome too if you feel adventurous and have access to hardware or a software emulator.
