fix: Fix sw64 gcc not support pie by default

[wangrong1069]

Add the -fPIE parameter via CMAKE_POSITION_INDEPENDENT_CODE. Add the -pie parameter via target_link_options.

Log: Update compiler flags for security enhancements
Bug: https://pms.uniontech.com/bug-view-339563.html

Summary by Sourcery

Enable position-independent code and PIE linking for all targets to address sw64 GCC default PIE support issues.

Build:

• Enable global position-independent code generation via CMAKE_POSITION_INDEPENDENT_CODE.
• Add -pie linker options for daemon, logger, searcher, and server targets to produce PIE binaries.

Reviewer's Guide

Enables position-independent code globally and links all main executables with PIE on sw64 by setting CMake’s global PIC flag and adding -pie link options to core targets.

File-Level Changes

Change	Details	Files
Enable global position-independent code generation for all targets.	Turn on CMAKE_POSITION_INDEPENDENT_CODE so compiled objects are built with -fPIE/-fPIC as appropriate. Rely on CMake’s built-in handling to propagate PIC/PIE to supported languages and platforms instead of manually adding -fPIE flags.	CMakeLists.txt
Link primary binaries as PIE executables for improved security and sw64 compatibility.	Add -pie link option to the daemon target via target_link_options. Add -pie link option to the logger executable target via target_link_options. Add -pie link option to the searcher executable target via target_link_options. Add -pie link option to the server executable target via target_link_options.	src/daemon/CMakeLists.txt src/logger/CMakeLists.txt src/searcher/CMakeLists.txt src/server/CMakeLists.txt

Hey - I've left some high level feedback:

• Enabling CMAKE_POSITION_INDEPENDENT_CODE globally may affect all targets (including shared libraries); consider restricting this to the specific executables or to the sw64 toolchain via appropriate CMake conditionals.
• The use of target_link_options requires a newer CMake version than the current cmake_minimum_required(VERSION 3.1.0); either bump the minimum required version or gate this behind a version check and use a fallback for older CMake.
• The -pie link option is added unconditionally; consider applying it only when using GCC on sw64 (or when the compiler/linker supports PIE) to avoid build issues on other platforms/toolchains.
