[PATCH v1 1/3] riscv: Add multiarch support for strcpy

[Yao Zihong]

Hi Jeff,

Thanks for the quick review - much appreciated. I’ve been catching
up on prior RISC-V string/multiarch discussions; if there’s specific
context I should revisit, pointers would be welcome. It’s reassuring
to know this aligns with what was being considered. I’ll wait for
feedback on the rest of the series before proceeding, as you suggested.

Best,
Zihong
