More updates to build optimization settings.
- Don't pass -s, this doesn't really help anything. The way we will have
to generate our final executables is with -g, and then strip them, since
we will need to keep the original for its symbols.
- Only gc sections in official build. This might slightly improve release
link time (at the cost of size). This allows release to build with GOLD.
