The condition needs to be quite a bit more complicated. For example,
my Windows fate box can compile DXVA2 just fine, however because its a
headless server machine, it doesn't have a GPU actually capable of
using DXVA2, so the test somehow needs to take this into account.
The same really goes for the mingw32 machines, which can build but not
run DXVA2.

Since everyone seems adamant to get this commited, i will try to do a
proper technical review of the DXVA2 usage after newyears. I also have
two H.264 DXVA2 patches for Intel GPUs in the pipeline which i need to
cleanup and submit.
