Guess what, that never landed and bug 1284803 broke this again.

Meh, considering the upcoming Debian stretch release targets mips32r2 instead of mips2, and that new target supports the pref opcode by default, it builds fine on the upcoming Debian stable. I'll carry the patch in Debian for older releases, but considering the patch is not applied upstream and this will break again, I don't think it's worth fixing in Gecko.
