[yocto] ipk zImage in master-next

[Trevor Woerner]

When packaging a zImage kernel for IPK in master-next the following
error shows up:

| kernel-image-zImage-4.1.2-fslc+g95d9e15
| *** Error: Package name  contains illegal characters, (other than
[a-z0-9.+-])

It looks like the newer kernel.bbclass is much more sophisticated about
generating package names than before.

Has anyone else seen this? Is there a simple way of saying "the type is
zimage where packaging for ipk is concerned but zImage otherwise"?

Best regards,
