Replace git@ with https://

[ioerror]

The current build-csky-gcc.py attempts to clone with the git command using [email protected]. This invokes the ssh command which required credentials. I replaced it with git clones that use https rather than git over ssh. I don't think this is strictly needed but I found it useful:
