rtthread-1.2.0-alpha版本 arm9系列编译问题

1、编译环境：ubuntu11-04，编译工具包：arm-2007q1（内含gcc工具arm-none-linux-gnueabi和libc库）
2、关掉NEWLIB和PTHREAD选项，编译at91sam9260和mini2440
3、出现同样的错误：
```LINK rtthread-at91sam9260.axf
build/libcpu/arm/at91sam926x/start_gcc.o: In function `_start':
/RT-Thread-1.2.0-Alpha/libcpu/arm/at91sam926x/start_gcc.S:(.init+0x0): multiple definition of `_start'

collect2: ld returned 1 exit status
scons: *** [rtthread-at91sam9260.axf] Error 1
scons: building terminated because of errors.```

4、查看libc_nonshared.a，__init_array_start等确实都为未定义符号。
5、请问是需要更换libc库吗？有没有直接可用的编译工具包，替换即可？
