This is a great idea, it seems to work on Debian at least; I set up a riscv64 
chroot using debootstrap and qemu-user:

apt install debootstrap qemu-user-static binfmt-support 
debootstrap --arch=riscv64 --keyring 
--include=debian-ports-archive-keyring unstable /tmp/riscv64-chroot 
chroot /tmp/riscv64-chroot

Then install the packages and everything
apt install binutils git make gcc nyacc guile-3.0-dev
git clone https://github.com/laanwj/guix-mes.git
git clone --recurse-submodules https://github.com/laanwj/guix-mescc-tools
cd guix-mescc-tools
cd ..
export PATH="/root/guix-mescc-tools/bin:$PATH"
cd guix-mes
./configure --with-bootstrap

This worked here to get a bin/mes-gcc and bin/mes-mescc
A full qemu-system should be even more "realistic" but will likely be 
noticeably slower.
