Committed, thanks.

While doing a test build I noticed that u-boot nowadays needs dtc:

  CHK     include/generated/timestamp_autogenerated.h
  UPD     include/generated/timestamp_autogenerated.h
./scripts/dtc-version.sh: line 17: dtc: command not found
./scripts/dtc-version.sh: line 18: dtc: command not found
*** Your dtc is too old, please upgrade to dtc 1.4 or newer
Makefile:1297: recipe for target 'checkdtc' failed
make[1]: *** [checkdtc] Error 1
make[1]: *** Waiting for unfinished jobs....
  UPD     include/config/uboot.release
make[1]: *** wait: No child processes.  Stop.
package/pkg-generic.mk:156: recipe for target '/home/peko/source/buildroot/output/build/uboot-2015.07/.stamp_built' failed

So perhaps we should consider adding host support to our dtc package and add
host-dtc to the uboot dependencies?
