1、vendor/mediatek/proprietary/hardware/ril/fusion/libril 编译生成librilfusion
2、vendor/mediatek/proprietary/hardware/ril/fusion/rild 编译生成mtkfusionrild 手机路径: /vendor/bin/hw/mtkfusionrild
3、vendor/mediatek/proprietary/hardware/ril/fusion/mtk-ril 编译生成libmtk-ril 手机路径: /vendor/lib64/libmtk-ril.so
其中librilfunsion编译链接mtkfusionrild中
