编译poco库找不到shm_open方法

【问题描述】

1、编译poco库是找不到shm_*相关的函数

clang++: warning: argument unused during compilation: '--gcc-toolchain=/home/yyx/kuwoMusic/ohos/ohos-sdk/linux/native/llvm' [-Wunused-command-line-argument]

【运行环境】

SDK版本：version-Master_Version-OpenHarmony_4.0.10.5-20230824_120921-ohos-sdk-public_monthly.tar.gz

shm_库是glibc的，ohos默认用的musl库，名字不一样，看看sys/shm.h
