Subject: [PATCH] mkimage: check environment for dtc binary location
Currently mkimage assumes the dtc binary is in the path and fails
otherwise. This patch makes it check the DTC environment variable first
for the dtc binary and then fall back to the default path. This makes
it possible to call the u-boot build with make DTC=... and build a fit
image with the dtc binary not being the the default path.
