Hello_world doesn't work for Arria 10 ubuntu 14.04

Altera's support says that they cannot reproduce the problem on their system. They say that the compilation on their machine gets defaulted to the standard PR flow which works fine (as it also does on my environment). However, they have changed something in the flat flow and people should not be using that anymore. The problem you guys are facing is very likely because you are being somehow defaulted to the flat flow. I even tried using the "--bsp_flow top" switch on my own environment, and it works and produces the same output as when the switch is not used. However, this switch does not enforce the default flow if the flat flow is enforced using the "ACL_QSH_COMPILE_CMD" environmental variable.
