See https://wiki.osdev.org/GCC_Cross-Compiler
In summary:
Download the gcc and binutils source.
Configure binutils with --prefix=$DIR --target=riscv64-unknown-elf for
some $DIR.
Run make && make install.
Configure gcc with the same --prefix and --target options.
Run make && make install.
If you want a hosted target like riscv64-unknown-linux-gnu for
compiling user-space programs, then you'll need to have a copy of the
target headers and libraries available, and point GCC to them with the
--sysroot option.
