If we try to build using external dtc using
make DTC=dtc
we get a confusing error like
make[2]: *** No rule to make target 'arch/x86/dts/bayleybay.dtb', needed by 'dtbs'. Stop.
Workaround is to use
make DTC=$( which dtc )
which gives make a full path, so the dependency is satisfied.
This was introduced by commit d50af66 kbuild: add dtc as dependency on .dtb files
and we extend it so it calls which automatically (similar to scripts/dtc-version.sh)
