How can I Build libyuv so for Android x86 ?

[GoogleCodeExporter]

I want build libyuv so on android .
armeabi-v7a and armeabi-v8a have succeed,but for x86 will link failed.
I use NDK r10-d,and GCC 4.9.

Below is my andoird.mk and errors:

Do you have any idea ? Is there something wrong with the android.mk?

I'm not set up to test this locally, but will update android.mk with the 
current lst of files at least.

First change:
SumSquareError_SSE2 is from compare_posix.cc
Add that.

r1280 adds neon64 but otherwise the android.mk in libyuv is up to date.
https://webrtc-codereview.appspot.com/39109004

the mk file you show is missing the _posix.cc files that contain those 
functions.
Add them and you should be good.

no further change on my end for now.
Can you verify that the android.mk in libyuv r1280 works for you?
