Looks like pipe2 may be unavailable on macOS: saleyn/erlexec#153

[epoupon]

Hello! Would you mind testing the fix-macos-build branch?
You can also cherry pick 777c360 if you don't want to get the updates made on the develop branch

[barracuda156]

@epoupon Thank you! Your fix works, the only minor problem remaining was this: #524
With that, the build succeeds now.

[barracuda156]

@epoupon Looks like it even runs! On 10.6 on PowerPC:

[epoupon]

Good news!
Did you manage to actually use it?

[barracuda156]

@epoupon I have just fixed the build, need to read documentation to see how to use it. But curious now :)

Could you review my PR btw?
