Describe the problem

Provide the exact sequence of commands / steps that you executed before running into the problem
When building Tensorflow from source when the TMP environment variable is not set, then following warning is shown:

Auto-Configuration Warning: 'TMP' environment variable is not set, using 'C:\Windows\Temp' as default

Naturally, I would expect it to default to something. However, I'm on a Linux computer, not a Windows computer. On Linux, it should default to something sensible (e.g. /tmp, or the current directory), instead of C:\Windows\Temp - which clearly isn't going to work - as on Linux this is not a valid file/directory path.

Any other info / logs
Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached.
