Control: reassign -1 ftp.debian.org According to the build logs, all lib*-*-cross packages have optional priority, so it needs to be adjusted for the archive.
That should be done for all lib*-*-cross packages built by gcc-10-cross, gcc-10-cross-ports, gcc-10-cross-mipsen, gcc-9-cross, gcc-9-cross-ports. I haven't checked gcc-10 and gcc-11 cross packages in experimental.
