Bug#824665: openbios-sparc: missing QEMU,cgthree.bin file

[Mark Cave-Ayland]

Note that the QEMU,cgthree.bin binary was first added to QEMU git master
in October 2013 in time for the 2.0 release so this bug actually affects
all of -backports, -stable, -testing and -unstable packages.


ATB,

Mark.
