Bootstrap build of Portola on Alpine

[Mikael Vidstedt]

Josh,

Did you have a chance to look at which file generates the warning/error?

Also, with the latest changes in the portola forest you should (hopefully) be able to drop the —build and —host configure arguments. If you happen to have a chance to try that let me know how it works out for you!

Cheers,
Mikael
