Build support for unknown archs - Loongarch in my case

[kant2002]

I'm building runtime on the Loongarch hardware and I discover that dotnet by itself very reliant on the arch-specific nugets.
Also even if I have SDK built for loongarch I still face some issues which is very delicate in nature.

For example self-contained apps require Microsoft.NETCore.App.Runtime.linux-loongarch64 and Microsoft.AspNetCore.App.Runtime.linux-loongarch64. See dotnet/linker#3130 (comment)

• so who and where should distribute these bits, and under what name when they would be eventually produced? What interim solution for these kind of issues exists? Cannot create layout on unknown arch Loongarch #78854

• Similar to this Loongarch add option to disable building Crossgen2  #78749 which is asking for a way to disable Crossgen2 at build level.

• Also Mono does not supported on Loongarch How to disable building of Mono on Loongarch #78796

Hi, @jkotas
The https://github.com/dotnet/dotnet should be consider the LoongArch64.

Is there some discussion about it ?
Maybe my experience about construction the SDK3.1, SDK6.0, SDK7.0 for LoongArch is helpful.

dotnet/arcade#11584 is announcement for dotnet/dotnet. You can read more about that in the announcement. dotnet/arcade has the design documents and the discussions for dotnet/dotnet.

For example, Red Hat is building S390 port using https://github.com/dotnet/source-build today, and they will switch to dotnet/dotnet once it becomes ready. dotnet/dotnet is a better way to do source-build. I would expect that LoongArch64 can be on the same plan.
