As I didn't see this bug happening for quite some time (I even forgot about
it), I did some investigations:
With v3.7+, zImage is not overwritten when we are doing a "make uImage", so DTB
is appended correctly.
But versions before v3.7 overwrite the zImage.

bisecting:
cd linux
git bisect start
git bisect good v3.6
git bisect bad v3.7
git bisect run ../test_zImage_overwrite.sh

(script provided)

here is the bisect result :
c353acba28fb3fa1fd05fd6b85a9fc7938330f9c
kbuild: make: fix if_changed when command contains backslashes

=> that means that appending DTB to uImage only works for kernel >=
v3.6-6674-gc353acb in buildroot.
