I know at least one user has been caught out by this, and I was as an
old version of the dtb was where I was expecting the new one to be.

When we move to a GENERIC kernel for armv6 I would not expect
FDT_DTS_FILE to be set, but for a single board kernel config it can
help as the user doesn't have to search around for dtc in the case it's
not installed on the build host.
