What steps will reproduce the bug?

Build on ppc64el

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

To build on that architecture. Nodejs has a long history of being perfectly buildable on ppc64el on debian.

What do you see instead?
