powerpc/bootwrapper: Allow user to specify additional default targets

Browse source 
It is inconvenient to add additional default targets to the bootwrapper
Makefile for each new board supported which just needs a different dts
file.  This change allows the defconfig to specify additional build
targets.

List additional targets to be built by the bootwrapper here (separated
by spaces). This is useful for targets that depend of device tree
files in the .dts directory.
Targets in this list will be build as part of the default build
target, or when the user does a 'make zImage' or a
'make zImage.initrd'.
