Bug ID: 51206
           Summary: Wine fails to load a stripped PE version of ntdll.dll
           Product: Wine
           Version: 6.9
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Using strip on a PE version of ntdll removes 'Wine builtin DLL' marker from the
DOS header and leads to inability to load it:

$ wine winver
wine: failed to load /home/../wine32/dlls/ntdll/ntdll.dll.so error c0000135
0024:err:environ:run_wineboot failed to start wineboot c00000e5

Older versions of llvm-strip (before 11.0.0) also used to replace DOS stub by
an internal version, however starting from 11.0.0 llvm-strip retains existing
DOS header.

Stripping other DLLs is not that fatal, they just lose their "builtin" flag.
