redist-installer.csproj : error NU1101: Unable to find package microsoft.netcore.app.crossgen2.linux-s390x.

Our CI cross-builds that build for ppc64le and s390x are failing recently with:

 /workdir/dotnet/src/sdk/src/Installer/redist-installer/redist-installer.csproj : error NU1101: Unable to find package microsoft.netcore.app.crossgen2.linux-s390x. No packages exist with this id in source(s): dotnet-eng, dotnet-libraries, dotnet-libraries-transport, dotnet-public, dotnet-tools, dotnet-tools-transport, dotnet10, dotnet10-transport, dotnet6, dotnet6-transport, dotnet7, dotnet7-transport, dotnet8, dotnet8-transport, dotnet8-workloads, dotnet9, dotnet9-transport, richnav, vs-impl. PackageSourceMapping is enabled, the following source(s) were not considered: prebuilt, previously-source-built, reference-packages, source-built-aspire, source-built-aspnetcore, source-built-command-line-api, source-built-deployment-tools, source-built-diagnostics, source-built-emsdk, source-built-fsharp, source-built-msbuild, source-built-nuget-client, source-built-roslyn, source-built-roslyn-analyzers, source-built-runtime, source-built-source-build-externals, source-built-sourcelink, source-built-symreader, source-built-templating, source-built-transport-arcade, source-built-transport-aspnetcore, source-built-transport-cecil, source-built-transport-emsdk, source-built-transport-msbuild, source-built-transport-razor, source-built-transport-roslyn, source-built-transport-runtime, source-built-transport-xdt, source-built-vstest. [/workdir/dotnet/src/sdk/source-build.slnf]

The ppc64le and s390x don't support crossgen2, so the build should probably not be trying to restore them.

Thanks for letting me know and sorry for the regression. #46944 will fix this.
