[Support linking for Ubuntu Natty/ppc Gentoo/ppc and Gentoohttps://user-images.githubusercontent.com/92601458/143742909-11cfd3c8-5f33-48c6-99de-7afb4c480bbc.gz) Updated tuple detection for Gentoo/ppc based on current stage3 tarball

0e6f8740-1d2a-4afc-85fd-df25c3a603fd commented 13 years ago

That patch finds tuples from Ubuntu/ppc and Gentoo/ppc64 (the only two I have access to at the moment). I can update it for Fedora/ppc and Gentoo/ppc in a week or so, but I'd rather get this in first and provide a smaller patch for those distros later.

The patch above fixes the reported problem, but I'm still unable to link due to missing data from ToolChain.getFilePaths();
