走到降级gcc这一步时，因为ubuntu16.04自带的是gcc5.4.0，所以想要降级，但是搞了一天都搞不定。
已经安装了gmp-4.3.2,mpfr-2.4.2,mpc-0.8.1。并且添加了路径
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib
但是configure通过了，make不成功，原因如下：
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
Makefile:16229: recipe for target 'configure-stage1-target-libgcc' failed
make[2]: *** [configure-stage1-target-libgcc] Error 1
make[2]: Leaving directory '/opt/gcc-5.3.0'
Makefile:20383: recipe for target 'stage1-bubble' failed
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory '/opt/gcc-5.3.0'
Makefile:902: recipe for target 'all' failed
make: *** [all] Error 2
请问这是什么问题导致的？
谢谢！
