怎么编译出能在玄铁C910处理器上能执行的gdb二进制呢？

[supercatking]

我尝试下载了这个源代码，然后执行下面的命令进行编译，但是最终的到的./gdb/gdb程序是个X86_64上的gdb，不是我想要的在玄铁处理器上能跑的gdb。请问正确的操作时什么？
./configure --target=riscv --with-sysroot=/home/xxx/Xuantie-900-gcc-linux-5.10.4-glibc-x86_64-V2.6.1/sysroot
make

=======below is compiled gdb for your reference ========================
xxx@user-OptiPlex-5090:~/xuantie/binutils-gdb-xuantie-binutils-gdb-2.32$ file ./gdb/gdb
./gdb/gdb: ELF 64-bit LSB pie executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=e33b0fc807302620100a4e7a007b8f3d33e7f540, for GNU/Linux 3.2.0, with debug_info, not stripped

Thanks!
