Carthage: Build framework regardless of prebuilt version

[dersvenhesse]

I'd really like an option to force build a framework regardless of a prebuilt version in the releases folder. This might be really helpful, especially when the latest prebuilt version was build with an old version of Xcode. A flag like carthage update --ignore-prebuild would check out all projects instead downloading the *.framework versions.

Or am I missing something and this is already possible?

Yes, we already have the option! --no-use-binaries is what you want.
