crossgen2 is linked against libraries from bootstrap packages

[corngood]

I found this while packaging dotnet 10.0.0-preview.1 for nixpkgs: NixOS/nixpkgs#385259.

This is the link task used to build crossgen2 on 9.0.2:

 573:2>Target "LinkNative" in file "/var/tmp/nix-shell.s0QLph/dotnet-9.0.2/src/runtime/artifacts/bin/coreclr/linux.x64.Release/build/Microsoft.NETCore.Native.targets" from project "/var/tmp/nix-shell.s0QLph/dotnet-9.0.2/src/runtime/src/coreclr/tools/aot/crossgen2/crossgen2_publish.csproj" (target "ComputeLinkedFilesToPublish" depends on it):

       Done executing task "Exec".

This is a problem for us because we patch the runtime in order to help it find system libraries. 9.0 linked against e.g. src/runtime/artifacts/bin/coreclr/linux.x64.Release/aotsdk/libbootstrapper.o, but 10 links against src/runtime/artifacts/sb/package-cache/runtime.linux-x64.microsoft.dotnet.ilcompiler/10.0.0-preview.1.25080.5/sdk/libbootstrapper.o.

One thing to note is that we're bootstrapping with 10.0.100-preview.1.25120.13 instead of 10.0.100-preview.1.25078.4, because the latter is not on https://dotnetcli.blob.core.windows.net/dotnet/release-metadata/10.0/releases.json.

@NikolaMilosavljevic - Can you help investigate? TIA.

[corngood]

I believe this was broken by dotnet/runtime@3f28b1a

It no longer sets IlcSdkPath etc.

[corngood]

@agocke sorry for the ping, but this seems to have originated with dotnet/runtime#107772, which is locked.

There was a comment on that thread that sounds like it's imagining the same problem:

I think however we ship crossgen2, we should ship it on equivalent runtime bits.

I'm still not sure if this is intentional, and if not, whether it should be a source-built or runtime issue.

For now I'll see if I can get crossgen2_publish.csproj to use the correct libs.

[corngood]

dotnet/runtime#105004

This may be relevant too.

[NikolaMilosavljevic]

@agocke it was mentioned up in comments (#4920 (comment)) that your change dotnet/runtime@3f28b1a has regressed this. This comment, in your PR, is interesting, and perhaps the reason for the change:

There's also no way to _not_ use LKG bits. That's left as future work.

Presumably, the use of LKG version of libbootstrapper.o is intentional. Is that correct? Is there a way to not use LKG in source-build?

In my local source-build I see two copies of libbootstrapper.o file that are identical:

./bin/coreclr/linux.x64.Release/aotsdk/libbootstrapper.o
./bootstrap/fedora.41-x64/aotsdk/libbootstrapper.o

Build is referencing this object file from the second location (LKG?).
