Big +1 for this from my side. Currently, the hybrid builds are a complete mess. For example, you can't use GCC4 and link OpenSSL on a gcc2h build because the optional package is either for gcc2 or gcc4 - no hybrid packages. FatELF would solve that issue very elegantly. It would also make it very easy for 3rd party applications to just distribute one binary for every architecture, instead of limiting it to x86 because cross-compilation is extra-effort. That would really be useful for PPC/ARM, so developers don't need to set up extra crosstools, but already have all libs they need on-board for other archs. -- Jonathan
