release/8.0 branch doesn't build with .NET 8 RC1

Trying to build the `release/8.0` branch in various configurations using .NET 8 RC1 leads to the following different errors on macOS:

* Mono builds:
```console
% ./build.sh mono -c Release
...
/usr/local/share/dotnet/sdk/8.0.100-rc.1.23463.5/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(90,5): error NETSDK1212: IsTrimmable is not supported for the target framework. Consider multi-targeting to a supported framework to enable trimming, and set IsTrimmable only for the supported frameworks. For example: [/Users/alklig/work/dotnet-runtime/runtime-net8/Build.proj]
/usr/local/share/dotnet/sdk/8.0.100-rc.1.23463.5/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(90,5): error NETSDK1212: <IsTrimmable Condition="$([MSBuild]::IsTargetFrameworkCompatible('$(TargetFramework)', 'net6.0'))">true</IsTrimmable> [/Users/alklig/work/dotnet-runtime/runtime-net8/Build.proj]
```
* CoreCLR:
```console
% ./build.sh clr -c Release

```


Libraries builds (`./build.sh libs -c Release`) seem to work.
