Created attachment 838585 [details] gcc build log, emerge info I'm following this guide: /wiki/Cross_build_environment and the build fails with the default make.conf which contains ~{ARCH} in the ACCEPT_KEYWORDS field. Additionally, the following use change was needed to build @system: sys-apps/util-linux -su. The attached emerge info was from after I made the changes, so it may not be totally relevant, but the build log is from the failed build.
