Linux WiiMote (bluetooth) support

[maggu2810]

If the WiiMote support is build, the file <bluetooth/bluetooth.h> is also included, e.g. because of the bt_get_... functions.
The file comes from the Bluez library.
Recent versions break C++ support (casting void* to anything). So the most distributions are using the following patch to allow usage with C++ code:

Because you are using the C++x0 standard, the keyword "typeof" is not available but __typeof__ is (for gcc).
Until Bluez is changing something, the following patch allows compilation again:

I also reported the typeof issue to the Bluez mailing list:
