移植版本：libsocketcan-0.0.10 和 canutils-4.0.6

libsocketcan编译:

./configure --prefix=$PWD/../out  --host=aarch64-linux-gnu CC=//home/alientek/asd/rv1126_rv1109/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc && make && make install

• 修改configure 文件2604行：ac_ct_CC=$ac_cv_prog_ac_ct_CC为ac_ct_CC=“aarch64-linux-gnu-gcc”

• 修改/config/autocof/config.sub文件
  241行：添加 | aarch64 | aarch64_be
  318行：添加| aarch64-* | aarch64_be-* \

canutils编译:

./configure --prefix=$PWD/../install --host=aarch64-linux-gnu CC=/home/alientek/asd/rv1126_rv1109/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc libsocketcan_LIBS=-lsocketcan LDFLAGS=-L/home/alientek/tool/socketcan/out/lib/ libsocketcan_CFLAGS=-I/home/alientek/tool/socketcan/out/include CFLAGS=-I/home/alientek/tool/socketcan/out/include && make && make install
