错误原因

文件之前在inter架构上被编译过，产生了编译文件*.o，
.o文件是inter架构（x86）系统上的，不能在ARM架构上继续使用。

解决方法

运行：make clean或者删除*.o文件

root@linaro-alip:/home/linaro/Downloads/EMB3581/Python-3.7.3# make clean
find . -depth -name '__pycache__' -exec rm -rf {} ';'
find . -name '*.py[co]' -exec rm -f {} ';'
find . -name '*.[oa]' -exec rm -f {} ';'
find . -name '*.s[ol]' -exec rm -f {} ';'
find . -name '*.so.[0-9]*.[0-9]*' -exec rm -f {} ';'
find build -name 'fficonfig.h' -exec rm -f {} ';' || true
find build -name '*.py' -exec rm -f {} ';' || true
find build -name '*.py[co]' -exec rm -f {} ';' || true
rm -f pybuilddir.txt
rm -f Lib/lib2to3/*Grammar*.pickle
rm -f Programs/_testembed Programs/_freeze_importlib
find build -type f -a ! -name '*.gc??' -exec rm -f {} ';'
rm -f Include/pydtrace_probes.h
rm -f profile-gen-stamp

重新编译，大吉大利
