There should be no difference between Linux and Windows (only between
TCG and KVM).

I'm not sure. The above command line works for me after building OVMF
like this:
build -p OvmfPkg/OvmfPkgIa32X64.dsc -a IA32 -a X64 -b DEBUG -t GCC49 -n 4
I'm using commit 89a8115 ("BaseTools: Support recent versions of cx_freeze.",
2016-03-15) of OVMF.
