patches for emulators/qemu on DragonFly

[Patrick Georgi <patrick%georgi-clan.de@localhost>]

Hi,

attached are three patches to make emulators/qemu build on DragonFly

patch-ba removes an unnecessary include (I assume it shouldn't be necessary 
anywhere, and inclusion fails with an error that it should not be used by 
userland applications)

patch-bb makes qemu build without librt on DragonFly

patch-bc disables the stack protector for op.c, as dyngen fails because of it 
when parsing op.o


Regards,
Patrick Georgi
