[PATCH] Always -lntdll for all cygming targets [PR113501]

[Shengdun Wang]

From: Shengdun Wang <uwgghhbcad@gmail.com>

The mcf thread has already linked to -lntdll, and it's confirmed that even Windows 95 includes ntdll.dll. Additionally, if users do not use any functions from ntdll directly, the inclusion of -lntdll does not result in linking to it. Therefore, I propose making it a default toggle to simplify compilation for Windows.

On windows 95, if we do -lntdll, it won't still run. I have tried and confirmed it.
