busybox 1.27.2 cross compile

안녕하세요~

busybox를 크로스컴파일 하는데 어려움이 있어, 고수님들의 노하우를 알고자 질문합니다.

busybox 1.27.2는 (https://www.busybox.net/) 에서 직접 다운로드를 하였고,

Host PC에는 Ubuntu 16.04.3 LTS server 가 설치되어 있습니다.
더불어 크로스컴파일러는 sudo apt-get install gcc-4.9-arm-linux-gnueabi 를 하여 설치가 되었습니다.
(*크로스컴파일러 설치 경로 : /usr/bin/)
(*ls /usr/bin 결과)

arm-linux-gnueabi-as

arm-linux-gnueabi-ranlib
arm-linux-gnueabi-readelf
arm-linux-gnueabi-size
arm-linux-gnueabi-strings
arm-linux-gnueabi-strip
....

이후 Busybox 디렉토리에서 Makefile을 수정하였습니다.

....
288
289 # Make variables (CC, etc...)
290
291 AS = $(CROSS_COMPILE)as
292 #CC = $(CROSS_COMPILE)gcc
293 CC = $(CROSS_COMPILE)gcc-4.9
294 LD = $(CC) -nostdlib
295 #LD = $(CROSS_COMPILE)ld
296 CPP = $(CC) -E
297 #AR = $(CROSS_COMPILE)ar
298 #NM = $(CROSS_COMPILE)nm
299 AR = $(CROSS_COMPILE)gcc-ar-4.9
300 NM = $(CROSS_COMPILE)gcc-nm-4.9
301 STRIP = $(CROSS_COMPILE)strip
302 OBJCOPY = $(CROSS_COMPILE)objcopy
303 OBJDUMP = $(CROSS_COMPILE)objdump
304 PKG_CONFIG ?= $(CROSS_COMPILE)pkg-config
305 AWK = awk
306 GENKSYMS = scripts/genksyms/genksyms
307 DEPMOD = /sbin/depmod
308 KALLSYMS = scripts/kallsyms
309 PERL = perl
310 CHECK = sparse
311
....

이제 "make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm" 를 실행하였는데 완료되지 못하고 중간에 에러가 발생합니다. 아래는 컴파일 과정 일부분 입니다.

여기서 에러의 원인을 정확히 모르겠습니다.
저는 "ld-linux.so.3: file not recognized: File format not recognized" 메시지가 이 문제를 해결하는데 도움이 될 줄 알고 열심히 찾아봤지만, 해결책을 찾지 못했습니다. ㅠㅠ

혹시 이 부분에 대해 무엇이 문제이고, 어떤 방법이 틀린 것이었는지, 또는 어떤 부분이 누락이 되어서 그런 것인지,
알고 계신 고수님들이 계시다면 부디 조언을 부탁드립니다.

감사합니다.
