[yocto] linux-yocto defaulting to 3.4.52 for new qemuarmhf.conf

[Elvis Dowson]

Hi,
      I created a new qemuarmhf.conf, to build using armv7a vfp and neon. 

In the linux-yocto_3.8.bb recipe, I explicitly specified SRCREV_machine_qemuarmhf and added qemuarmhf to the list of COMPATIBLE_MACHINES.

For some reason, it still refuses to build using kernel 3.8, and keeps defaulting to 3.4.52.

I know I can over-ride it in my local.conf by setting a PREFERRED_VERSION_virtual/linux ="3.8" , but I'd like to know what I've missed, to get it to work by default, without setting the over-ride in my local.conf.

Thanks!

Best regards,

Elvis Dowson
