Okay, I see that we are already handling this special case in
FindwxWidgets.cmake by using "sh wx-config" in execute_process calls.
This means the module is already aware that the wx-config it is running
is not a Windows tool.  The proposed change merely adds support for
treating the output accordingly.

I've applied the change with minor tweaks and tried to explain this
in the commit message:
