The mainline builds are all cross-built rather than native built. Binaries like fixdep etc are used by the build process, and since its a build on amd64 those binaries are complied for amd64. It is very resource intensive to build these unsupported kernels native for each architecture.
Also note that these kernels are not intended for production systems, and are made available for sneak peek/testing purposes only. These are unmodified upstream kernels built using the ubuntu config files. Or in other words.. these packages are "install at your own risk" and not supported in any way. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1665447 Title: kernel ppa is building amd64 files inside mainline ppc64el package Status in linux package in Ubuntu: Incomplete Bug description: Kernel PPA contains a files that are compiled against amd64 instead of ppc64el.
