[ECOS] Can I also generate other outputs of gcc when build?

Thanks, but "-save-outputs" seems unrecognized when invoke arm-elf-gcc.
For example:
arm-elf-gcc -c  
-I/ecos-c/cygwin/opt/development/project/cpu_4c_lib/lib_install/include 
-I/opt/development/ecos/packages/language/c/libc/string/current 
-I/opt/development/ecos/packages/language/c/libc/string/current/src 
-I/opt/development/ecos/packages/language/c/libc/string/current/tests -I. 
-I/opt/development/ecos/packages/language/c/libc/string/current/src/ 
-finline-limit=7000 -mcpu=arm7tdmi -mno-short-load-words -Wall 
-Wpointer-arith  -Winline -Wundef -Woverloaded-virtual -g -O0 
-ffunction-sections -fdata-sections -fno-rtti -fno-exceptions   
-save-outputs -Wp,-MD,src/strcoll.tmp -o 
src/language_c_libc_string_strcoll.o 
/opt/development/ecos/packages/language/c/libc/string/current/src/strcoll.cxx

arm-elf-gcc: unrecognized option `-save-outputs'

I am using the prebuilt arm-elf-gcc from eCosCentric, the version is 3.2.1
