Installing and cross building binaries is a bit out of scope for QEMU
(although QEMU is often used to run a guest userspace with "native"
compilers if the cross compilers are hard to get hold of). The riscv32
compilers themselves are a bit of a pain to get hold of as not many
distros package them up.

Assuming you just want to run userspace code it's as simple as:

  ./qemu-riscv32 <program>

although you might want to setup binfmt_misc to automatically run your
riscv32 binaries.
