Subject: [PATCH] build: replicate macOS `-dead_strip` optimization on Linux

Added `-fdata-sections` and `-ffunction-sections` compiler flags to work
with `--gc-sections` on Linux. This combination achieves similar dead
code elimination as macOS's `-dead_strip`, reducing binary size and
resolving undefined symbol issues. Ensures consistent optimization
across macOS and Linux builds.
