#     powerpc/boot: Fix build of dts/fsl
#     
#     The lkp robot reported that some configs fail to build, for example
#     mpc85xx_smp_defconfig, with:
#     
#       cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8540ads.dtb.dts.tmp: No such file or directory
#     
#     This bisects to:
#       cc8a51ca6f05 ("kbuild: always create directories of targets")
#     
#     Although that commit claims to be about in-tree builds, it somehow
#     breaks out-of-tree builds. But presumably it's just exposing a latent
#     bug in our Makefiles.
#     
#     We can fix it by adding to targets for dts/fsl in the same way that we
#     do for dts.
#
