With a long $(srctree) that command is too large for /bin/sh -c and Make fails with "Argument list too long" while building a .dtb. Write the flags to a per-target .dtc.flags.tmp file and pass @file to HOSTCC/CPP so the shell command stays short. This change requires GNU Make >= 4.0, since $(file ...) is not supported by Make 3.x.

We should likely fix this too. 94 # If the user is running make -s (silent mode), suppress echoing of 95 # commands 96 ifneq ($(filter 4.%,$(MAKE_VERSION)),) # make-4 97 ifneq ($(filter %s ,$(firstword x$(MAKEFLAGS))),) 98 quiet=silent_ 99 endif 100 else # make-3.8x 101 ifneq ($(filter s% -s%,$(MAKEFLAGS)),) 102 quiet=silent_ 103 endif 104 endif Thanks, Michal
