All the code that relies on separating them uses the built-in defines
_WIN32 and _WIN64, or the corresponding machine defines (such as
_M_IX86, for MSVC 32 bit inline assembly).
Instead just link directly to it. This matches how the library is
linked/loaded in encConsole/h264enc as well.
Only the 2008 version project file is updated for now, since
the 2010 and 2012 ones are out of sync right now.
