Freeglut fails to build on kfreebsd* due to missing legacy/dev/usb/usb.h

[Anton Gladky <gladky.anton@gmail.com>]

Dear all,

there is a bug #678571 [1].
Freeglut fails to build on kfreebsd* due to missing legacy/dev/usb/usb.h:

freeglut_joystick.c:154:40: fatal error: legacy/dev/usb/usb.h: No such
file or directory

I have committed a fix [2], but I am not sure, whether it is correct.
The fghJoystickWalkUSBdev() function was actually blocked.

It would be good to know your opinion on that, comments and patches
are very welcome.

Thank you.

Anton
