The RISC-V Foundation defined semihosting as relative to the existing
ARM specification, so using a link to that is appropriate here.

Here's the current specification of the unprivileged ISA, which includes
the definition of semihosting

While it may be nice in some abstract sense to create a "better"
semihosting spec, that's not what the RISC-V foundation has decided to
do.
