At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined. This is wasteful when the system already has a suitable version available.
Update the Makefile logic to build dtc only if the version available is too old.
This saves about 3 seconds of CPU time on a clean build for me.

In the case of new enough host dtc this then fails on sandbox_spl, chromebook_minnie and others where we need to build spl/dts/dt-platdata.c with a python import error over lacking _libfdt.
I'm not sure if it has been long enough, but have the packages been updated to include pylibfdt?
I'm sending a new version of this patch that checks for that.
