OpenHarmony里有没有shadow文件，支持通过getspnam函数，从/etc/shadow 文件中读取用户的加密密码信息吗

【问题描述】

1. 我现在在编译三方库openssh，但是在make阶段报错，显示找不到getspnam函数，然后我去shadow.h和libcrypt.a里面找了，都没有找到gestpnam函数的实现，所以我想问一下OpenHarmony支持通过getspnam函数，从/etc/shadow 文件中读取用户的加密密码信息吗，假如不支持的话，就可以把shadow给禁用了

2. 运行的指令 ./configure --host=aarch64-linux CC=/home/wbk/opt/native/llvm/bin/aarch64-unknown-linux-ohos-clang CXX=/home/wbk/opt/native/llvm/bin/aarch64-unknown-linux-ohos-clang++ --prefix=/home/wbk/opt/output/openssh_v8 --with-ssl-dir=/home/wbk/opt/output/openssl_v8 --with-zlib=/home/wbk/opt//output/zlib_v8 CFLAGS="--sysroot=/home/wbk/opt/native/sysroot" LDFLAGS="-L/home/wbk/opt/native/sysroot/usr/lib -lcrypt"

3. 报错显示
