大神们好，我在安装libxml2库时遇到如下问题，大家帮忙指点指点：
虚拟机系统：Ubuntu16.04
ARM芯片：AM4378，Linux系统
待安装Libxml版本：libxml2-2.9.4
交叉编译链版本：gcc version 4.9.3 20150413 (prerelease) (Linaro GCC 4.9-2015.05)
安装编译方式：
（1）sudo ./configure --host=arm-linux CC=/usr/crosstools/gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++
（2）make
（3）make install
问题描述：
采用默认的config编译安装没问题，但生成的库libxml2.so，交叉编译工具arm-linux-gnueabihf-g++无法识别，所以尝试采用arm-linux-gnueabihf-g++进行编译，但不能正常编译，具体情况如下：
之前未指定arm-linux-gnueabihf-g++路径设置编译选项(sudo ./configure --host=arm-linux CC=arm-linux-gnueabihf-g++)，报错如下
checking whether the C compiler works... no
configure: error: in `/home/nextev/Softwores/libxml2-2.9.4':
configure: error: C compiler cannot create executables
指定arm-linux-gnueabihf-g++绝对路径后，./configure没问题，但编译报错如下

另外，只有采用默认的编译选项可以正常编译安装，g++、arm-linux-gnueabihf-gcc、arm-linux-gnueabihf-g++均无法用
大家多多指点啊，不胜感激！
