Description zen 2022-11-30 18:24:40 UTC

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.
