A newer one I just upgraded to indeed does. Interesting, --strip-all is the next best thing then, I think, so I'd suggest: $(objcopy-option, --strip-section-headers, --strip-all) With (untested): # objcopy-option # Usage: KBUILD_LDFLAGS += $(call objcopy-option, --strip-section-headers) objcopy-option = $(call try-run,\ $(CC) -x c /dev/null -c -o "$$TMPO"; $(OBJCOPY) $(1) "$$TMPO" "$$TMP",$(1),$(2)) >> OBJCOPYFLAGS_$@ = $your_options. >> >> >> Sidenote: We should add --error-rwx-segments depending on >> CONFIG_PBL_IMAGE_ELF. > > Is this a objcopy option? My objcopy doesn't seem to support this. See LDFLAGS_common += $(call ld-option,--no-warn-rwx-segments).
