Strange...
1) The string "opening dependency file" does not occur in my freshly pulled kernel
2) Line 268 is last line of ihex2fw.c

Could you try to do a "make modules_install V=1" to see the exact arguments supplied ti ihex2fw.c

I gave up on all the firmware stuff long time ago and has
never properly reviewed the implementation so I really
have no clue what is actually happening.

Walking through the 179 lines Makefile has not yet benn on my
"fun to do" list - and it most likely take a while before it hits it.
