[ Upstream commit efe84d408bf41975db8506d3a1cc02e794e2309c ]
When building with
$ HOST_EXTRACFLAGS=-g make
the expectation is that host tools are built with debug informations.
This however doesn't happen if the Makefile assigns a new value to the
HOST_EXTRACFLAGS instead of appending to it. So use += instead of := for
the first assignment.
Fixes: e3fd9b5384f3 ("scripts/dtc: consolidate include path options in Makefile")
