1.1 hi3559av100 交叉编译

hi3559av100:
export PKG_CONFIG_LIBDIR=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/aarch64-linux-gnu/lib64/

./configure --host=aarch64-himix100-linux-gcc --disable-shared  --without-jpeg  // --host的值有问题，下面的就可以

./configure --host=aarch64-himix100-linux --disable-shared  --without-jpeg CC=aarch64-himix100-linux-gcc CXX=aarch64-himix100-linux-g++
