while I run glibc-glibc-2.33.9000/configure --host=loongarch-linux-gnu, error happened as checking host system type... Invalid configuration 'loongarch-linux-gnu': machine 'loongarch-unknown' not recognized.
By reading the source code, I run as glibc-glibc-2.33.9000/scripts/config.sub loongarch-linux-gnu again, which is the line that directly caused the error. Throw adding set -x at glibc-glibc-2.33.9000/scripts/config.sub，I get the following msg:

新世界使用 rust 编译 librsvg，在编译其中一个库 proc-macro2 时，在链接阶段报错: undefined reference to main
详细信息如下：
