Error building quick-start example for RISC-V

Greetings! I tried to build the quick-start example for RISC-V [1] but got this error, please advise:

$ cargo build --target=riscv32imac-unknown-none-elf

error: `panic-probe` only supports Cortex-M targets (thumbvN-none-eabi[hf])

Thanks for bringing it to my attention. panic-probe only works on cortex-m. i recommend you to use the arm version of the command to build for now.

i will soon revamp the book and update the instructions properly. Currently, i am working on the Rust Embedded Drivers book.
