编译出错Relocations in generic ELF (EM: 62)

今天在交叉编译libnl的时候，出错了，信息如下：

/mnt/nfsroot/frank.yu/android-mbr-p212/factorytest/wifi/out/lib/libnl.a: error adding symbols: File in wrong format

错误信息是：libnl.a(family.o): Relocations in generic ELF (EM: 62)

通过查看静态库libnl.a中的文件 family.o， 发现elf64-x86-64，这个真是奇怪了

objdump -a libnl.a

cache.o:     file format elf64-little

重新解压了一个libnl-1.1.4.tar.gz，发现没有任何编译，lib目录竟然存在libnl.a， 原来是源码的上传者，使用的是x86-64的交叉编译器编译生成的libnl.a， 然后上传了。这样导致我这边出错了，然后把libnl.a删除了，重新编译就没有报错了。

rm lib/libnl.a
