2.28这个版本太老了，还没有支持LoongArch 的 ABI 2.0

2.28这个版本太老了，还没有支持LoongArch 的 ABI 2.0

具体的ABI是什么样的没研究过，但这个2.28版本是从pkg.loongnix.cn/loongnix上边下载的2.28最新版本

[yunhai2009]

另外发现一个问题，如果使用binutils-2.42 gcc12.4 glibc2.28生成的交叉编译工具链，生成的elf的标志(flags)为0x43，而龙芯官方公布的工具链编译生成的elf标志为0x3。请问是不是说binutils在新旧世界并不兼容？binutils-2.42只能生成新世界的elf，而龙芯公布的binutils-2.31.1只能生成旧世界的elf。 @sunhaiyong1978

是的，两者不兼容。
