>Description:
When I try running .NET programs compiled for Linux on NetBSD, I see
errors about failures to create CoreCLR.

>How-To-Repeat:
Example:
https://romvault.com/trrntzip/download/TrrntZip.NET210Linux.zip
file reports:
TrrntZipCMD: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=104b3fd6fc145ba98d58ca66e152744bc7f251b7, stripped
Running it gives:
Failed to create CoreCLR, HRESULT: 0x8007054F

The same happens when one downloads the .NET SDK from Microsoft and tries to run it.
Visit https://dotnet.microsoft.com/download/dotnet/3.1 and get "SDK 3.1.something"
from the left side of the web page, the Linux x64 version.
Unpack it (attention, it unpacks into ".") and run

./dotnet -h
Failed to create CoreCLR, HRESULT: 0x8007054F

The kdump between finding the correct executable and the error is quite short:
