How to build openjdk mobile project android platform successfully and how does the mobile project adapt to bionic C ?

[guoge (A)]

Hi mobile-dev,

                I want to build an android openjdk from the mobile project.(http://hg.openjdk.java.net/mobile/jdk9/)
                I followed the guide(http://openjdk.java.net/projects/mobile/android.html) but failed in the "make images" phase.
                I tried two versions of NDK toolchains(android-ndk32-r10b-linux-x86_64 and  android-ndk-r10e-linux-x86_64) and the followings are the configure and make images command outputs, could you help figure out why the project can't be built successfully?

                In addition, could you tell me how the mobile project adapts to the bionic C when bionic C lacks some functions the openjdk needs(such as ucontext.h, getpwuid_r etc.)?

                Thanks.
