The above is suboptimal. The $(call if_changed,uimage) will execute
$(cmd_uimage) if 1) prerequisites has changed or 2) the command to execute
has changed.
In the above case 1) is always true, otherwise we would not reach the
statement. So change it to $(call cmd,uimage) is the correct way.

The 'bug' is also present in ppc/boot/images
