ios7.1 - How to link with framework without arm64 support in Xcode 5.1?

Question

After upgraded a project on Xcode 5.1, Product > Build gives the following warning and error:

ld: warning: ignoring file Dropbox/Dropbox.framework/Dropbox, missing required architecture arm64 in file Dropbox.framework/Dropbox (3 slices)

Undefined symbols for architecture arm64: "_OBJC_CLASS_$_DBPath", referenced from: objc-class-ref in DropboxViewController.o

It seems like the Dropbox.framework does not support arm64 yet.

What are the Xcode settings to remove arm64 support from the project to have a clean build?
