Stratix-IV QSYS generation Error

This issue is resolved by adding tool chains to the system. We may still have an issue with Windows 10 but at least the original issue is unblocked.

System : Ubuntu 18.04 LTS
Software : Quartus Prime Standard 20.1 / Stratix IV GX
Project : 4SGX230 Nios II MMU (Altera Reference)

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install build-essential

Now we can generate the HDL for qsys_ghrd_4sgx230 with no error.

Thanks,

Shige
