I would again suggest deferring adding such functions, especially the C 
ones, and instead helping with updating / reviewing RTH's optimized 
generic string functions posted a while back, and only adding 
RISC-V-specific ones if there is some clear reason RISC-V needs something 
non-generic for optimal performance.
