In commit96d9b94a98(Emscripten: Add platform modules, 2025-05-16, v4.2.0-rc1~607^2~3) this flag was added as part of an attempt to support shared libraries without requiring projects to set much themselves. That attempt was reverted by commitd361bf365e(Emscripten: Drop hard-coded -sMAIN_MODULE and -sSIDE_MODULE flags, 2025-09-18, v4.2.0-rc1~146^2). Also avoid hard-coding `-fPIC`. `POSITION_INDEPENDENT_CODE` is already enabled for shared library targets. Projects can enable it themselves where `-fPIC` is needed outside of shared libraries. Fixes: #27424 Issue: #27240
