From: Chen Qi <Qi.Chen@windriver.com>

On some Windows systems, symlinks are now allowed due to IT policy.
We need to be able to generate Windows SDK without symlinks.

To do this, a new variable, WINSDK_NO_SYMLINK, and a new bbclass,
mingw_sdk_handle_symlink.bbclass, are introduced to achieve this.

By default, things work as before; when setting WINSDK_NO_SYMLINK
to "1", SDK will replace all symlinks with the actual contents.
