Yes, I'm currently working off master. If I add the following qemuarmhf.conf file, and apply the patch to linux-yocto_3.8.bb, it still tries to compile linux-yocto_3.4.bb recipe. You should be able to reproduce this fairly easily at your end, with the current poky master. I'm not using any additional layers, just the core yocto default layers.

Filename: qemuarmhf.conf

#@TYPE: Machine
#@NAME: qemuarmhf
#@DESCRIPTION: Machine configuration for QEMU ARM Cortex A9 hard float.
