Hi Luca, please see the work around in my reply on this issue: #164

Hi @jzuckerman,
I did as you suggested in issue #164 and it worked.
However, I had to change the URLs that are reported in my previous screenshoot. Apparently, the problem is not related to ESP itself: https://lists.gnu.org/archive/html/qemu-discuss/2017-10/msg00046.html.
In particular, I had to do the following operations manually (I found the new URLs by searching for the "non-working" URLs on Google):

1. Cloning
   https://gitlab.com/qemu-project/dtc.git
   https://gitlab.freedesktop.org/pixman/pixman.git
   into
   ${ESP_ROOT}/_riscv32imc_build/riscv-gnu-toolchain/riscv-qemu/.

2. Cloning
   https://gitlab.com/qemu-project/SLOF.git
   https://gitlab.com/qemu-project/ipxe.git
   https://gitlab.com/qemu-project/openbios.git
   https://gitlab.com/qemu-project/openhackware.git
   https://github.com/rth7680/qemu-palcode.git
   https://gitlab.com/qemu-project/seabios.git
   https://gitlab.com/qemu-project/sgabios.git
   https://gitlab.com/qemu-project/u-boot.git
   https://gitlab.com/qemu-project/vgabios.git
   into
   ${ESP_ROOT}/_riscv32imc_build/riscv-gnu-toolchain/riscv-qemu/roms/.

3. Then, I commented lines 84 and 95 of ${ESP_ROOT}/utils/toolchain/build_riscv_toolchain.sh, similarly to what is suggested in #164.

4. Rerun the script.

The strange thing is that I already installed ESP and the "riscv32imc toolchain" on another CentOS7 machine (2 months ago) and I did not encounter this issue.

I hope my contribution can help you to solve this issue.
On my side, the issue can be closed.
Thanks

Thanks for the suggestions!
