[Libface-general] Various patches

[Hubert F. <hu...@fi...>]

Hi,

I couldn't find the bug tracker to post these.

Here are 4 patches. In order:


1. Don't force 32-bits on MacOS X. This does not make sense. Even my 
opencv is in 64 bits.

2. Log.h cause a warning on uninitialized struct field.

3. opencv include isn't different on Mac

4. the .pc should also indicate a dependency on opencv.

Cheers,

Hub
