说明：在Ubuntu 18.04上编译Yocto，出现的lzop配置自检失败的问题
2018-10-9 佛山顺德 Yangzf
/**********************************************************************
一、参考文章
https://community.nxp.com/thread/457348
二、解决方法：
将{yocto_path}/sources/poky/meta/recipes-support/lzop/lzop/x32_abi_miniacc_h.patch文件内容替换成下面内容：
Fix get of FLAGS register in x32 ABI,
x32 ABI requires to have 64-bit variable to store FLAGS register
instead of size_t that is 32-bit variable, this fix operand
type mismatch when try to pop previous pushf value.
