Please try meta-riscv here https://github.com/riscv/meta-riscv
the intructions are here
https://github.com/riscv/meta-riscv/blob/master/README.md

It will build its own toolchain once you have it up in qemu then you
can tweak conf/machine/include/tune-riscv.inc to add a new tune which
uses -march = rv64imafd
