Problems with building openblas on Android

[gaoqiang]

Hi, I was try to install openblas on android following https://github.com/xianyi/OpenBLAS/wiki/How-to-build-OpenBLAS-for-Android. And when I ran "make TARGET=ARMV7 HOSTCC=gcc CC=arm-linux-androideabi-gcc NOFORTRAN=1 libs", I got the following error:

Do you know why?

Something led to a broken definition of the "ar" tool, could you try the build script posted in #963 please ?
