#70075: dotnet-cli 8.0.4 : build for newer macos

 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.9.3
 Keywords:             |       Port:  dotnet-cli dotnet-sdk-6
-----------------------+-------------------------------------
 I installed `dotnet-sdk-6` and command `dotnet` from `dotnet-cli` does not
 work properly

 MacOS: 10.13.6

 MacPorts: 2.9.3

 {{{
 → dotnet
 dyld: Symbol not found: ____chkstk_darwin
   Referenced from: /opt/local/bin/dotnet (which was built for Mac OS X
 10.15)
   Expected in: /usr/lib/libSystem.B.dylib

 }}}

 The `dotnet-cli` match `dotnet-sdk-8` MACOSX_DEPLOYMENT_TARGET, but not
 `dotnet-sdk-6` min macos version that should still work on 10.13.

 `dotnet-cli` should be split to match `dotnet-sdk-6` and `dotnet-sdk-8`
 build target.

 The binaries from [https://dotnet.microsoft.com/download/dotnet/thank-
 you/sdk-6.0.422-macos-x64-binaries] work properly without dylib problems.
