源码编译gcc出错，大家帮忙看看

Question

错误信息如下

/usr/bin/ld: /root/gcc-4.9.2-build-try0/./gmp/.libs/libgmp.a(mp_set_fns.o): relocation R_X86_64_32 against `__gmp_default_allocate' can not be used when making a shared object; recompile with -fPIC
/root/gcc-4.9.2-build-try0/./gmp/.libs/libgmp.a: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
make[6]: *** [libjavamath.la] Error 1
make[6]: Leaving directory `/root/gcc-4.9.2-build-try0/x86_64-unknown-linux-gnu/libjava/classpath/native/jni/java-math'

在网上查了，说是要带"-fPIC"参数重编gmp，试过了，但是还是出错，求各位大神帮忙看看，谢谢！

这个 -fPIC加的参数对吗？
