errors on building Linux cross-compiler

[kgf]

This is the same issue as:
https://pulp-platform.org/community/show...php?tid=76

Sadly, as far as I see there, it also does not have a solution that seems to have found an answer. We can not replicate the behavior here, maybe someone from the community who has come across this and found a solution? I still suspect that the cross compiler is not in your PATH, i.e. the step mentioned below is missing, or not correct.. 

To build the Linux cross-compiler, pick an install path. If you choose, say, /opt/riscv, then add /opt/riscv/bin to your PATH now.
