Bug ID: 47484
           Summary: `winetricks -q dotnet20sp1` fails when compiled with
                    mingw (failure to relocate PE builtin ngen.exe)
           Product: Wine
           Version: 4.12.1
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

winetricks overrides ngen.exe as builtin-only. However, both the native
ngen.exe installed by the dotnet20sp1 installer and the PE builtin have the
same load address of 0x400000. The loader loads the native ngen first, and then
tries to load the PE builtin; the latter has to be relocated, but is compiled
without relocations.

I suspect the loader should be unmapping the native ngen before trying to load
the builtin one.
