dmd should output coff when compiling with -m64

Mine looks like this:

[Version]
version=7.51 Build 020

[Environment]
LIB="%@P%\..\lib"
DFLAGS="-I%@P%\..\phobos" "-I%@P%\..\druntime\import"
VCINSTALLDIR=C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\
WindowsSdkDir=C:\Program Files\Microsoft SDKs\Windows\v7.0\
LINKCMD=c:\dmd\bin\link.exe
LINKCMD64=%VCINSTALLDIR%bin\amd64\link.exe

VCINSTALLDIR and WindowsSdkDir may be different depending on the version 
of the installed windows SDK.
