[PATCH] D34853: Fix (benignly) incorrect GoogleTest specs in various lit configs.

Hi,

I believe that this "build mode" is intended for the Visual Studio MSVC build. This build is special in that it can produce builds for multiple configurations, e.g. Debug, Release & RelWithDebInfo, within the same top level build output directory. It is this configuration type that defines the "build mode". This means that the unit tests will only pick up the configuration that matches that of the lit that was run. Without the "build mode" I believe lit might end up running all configurations of unit tests that have been built, which is probably not the intended behaviour.

Cheers,
Andrew
