Have you read packages/hal/i386/pc/current/cdl/hal_i386_pc.cdl ? Or
maybe you ecos.ecc file?

objcopy is only called under a few conditions. eg. 

        cdl_option CYGBLD_BUILD_GDB_STUBS {
            display "Build GDB stub loader image"
            default_value 0
            requires { CYG_HAL_STARTUP == "FLOPPY" }
            requires CYGSEM_HAL_ROM_MONITOR
            requires CYGBLD_BUILD_COMMON_GDB_STUBS
            requires CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS
            requires ! CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT
            requires ! CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT
            requires ! CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT
            requires ! CYGDBG_HAL_COMMON_INTERRUPTS_SAVE_MINIMUM_CONTEXT
            requires ! CYGDBG_HAL_COMMON_CONTEXT_SAVE_MINIMUM
            no_define
            description "

                build process, but the final conversion from ELF image to
                binary data is handled by the platform CDL, allowing
                relocation of the data if necessary."
