Andorid7.1-x86 make: *** [ninja_

折腾了很久，不知道为什么 make -j8 的时候会报错：

ninja: Entering directory `.'
ninja: error: 'out/target/product/x86/obj/STATIC_LIBRARIES/libapf_intermediates/export_includes', needed by 'out/target/product/x86/obj/SHARED_LIBRARIES/libservicestestsjni_intermediates/import_includes', missing and no known rule to make it
make: *** [ninja_wrapper] 错误 1

于是乎，用 make iso_img -j8编译！没问题！
具体原因还在排查....
