产生的原因是我的UBUNTU是32位的，要求64位。

牛人给了一个解决方法 ： external/qemu/Makefile.common  externalqemu/Makefile.target 中关于-m64改为-m32

http://www.dewen.org/q/6600

进入你的android src目录：

修改：build/core/main.mk

from： ifneq (64,$(findstring 64,$(build_arch)))
改为： ifneq (i686,$(findstring i686,$(build_arch)))

还要修改其他一些mk file，比如：
external/clearsilver/cgi/Android.mk
external/clearsilver/java-jni/Android.mk
external/clearsilver/util/Android.mk
external/clearsilver/cs/Android.mk

把所有的LOCAL_CFLAGS += -m64 改为 LOCAL_CFLAGS += -m32

****grep所有的mk文件，把所有64改成32****
