Subject: [PATCH] Add support for xcompiler on Alpine 3.13

Problem: xcompiler on Alpine 3.13 was not found

Solution is to add "riscv-none-elf-gcc":

1. Add Edge to your repositories:
$ echo -e "http://dl-cdn.alpinelinux.org/alpine/edge/main\nhttp://dl-cdn.alpinelinux.org/alpine/edge/testing\nhttp://dl-cdn.alpine
linux.org/alpine/edge/community" >> /etc/apk/repositories
$ apk update
$ apk add gcc-riscv-none-elf
2. The xcompiler should be found at:
$ which riscv-none-elf-gcc
/usr/bin/riscv-none-elf-gcc
