We are building Tor Browser for Windows using mingw-w64, gcc 5.4.0 and
binutils.

A build done using binutils commit 4c2da80c2bdff7761eb5b3d9c03ffa0c9958b6b9 is
working fine.
A build done using binutils commit ca6f2be7f6bc638fd4fad48def1fae4ae4d7906e is
crashing when we try to start the browser.

In a debugger we can see a lot of messages like:

procedure "NtEnumerateKey" in DLL "ntdll.dll" is invalid
