x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES

- Wrong name was used for patchset
- Use https URLs from sourceforge to save one redirect
- gcc2 build fix at the proper place (previously a generated file had

Thanks to Sergio Baldovi for contributing those.
