With dotnet/runtime#58558, .NETFramework tfms which include a RID (i.e. net461-windows) aren't used and supported in dotnet/runtime anymore. Removing the support from the TargetFramework.Sdk as .NETFramework tfms with a RID aren't supported by NuGet anyways and throw.

I have found that when I've made a change to use the lld linker in July,
I've missed to push part of the change that was supposed to go to Arcade.

Without this change, the lld enabling flag is not used and we end up using
the default linker.

* Don't strip .NETFramework tfms

With dotnet/runtime#58558, .NETFramework tfms which include a RID (i.e. net461-windows) aren't used and supported in dotnet/runtime anymore. Removing the support from the TargetFramework.Sdk as .NETFramework tfms with a RID aren't supported by NuGet anyways and throw.

* Update Microsoft.DotNet.Build.Tasks.TargetFramework.Sdk.targets

…ional, the productVersion.txt stuff needs to succeed. (#7882)

* Add clang-versions used on modern FreeBSD versions.

This helps .NET build on FreeBSD.

* Update FreeBSD target

Current release is 12, not 11.

* Fix linking on FreeBSD.

These changes have previously been introduced in `dotnet/runtime`, but been reverted through automated updates later on.

This commit re-introduces them.

* Remove 3.9.
* Set 3.13 as default.
* Add 3.14.
