[meta-freescale] Invalid instruction with qemu-ppc64 for ppc64e6500

[Zhenhua Luo]

Hi Yi, 

Due to the ppc64 support limitation of qemu-native, please don't add the following line in local.conf, the core-image-sato can be built with default configuration. 

QEMU_TARGETS_append = " ppc64"


Best Regards, 

Zhenhua
