 - Align the default `_stext` to the alignment required by the `.text` section. Fixes
   the lld warning `address (...) of section .text is not a multiple of alignment (...)`.
     - Note: `_stext` is not auto-aligned if it's explicitly overridden by the user. It's their responsibility to align it, else the warning will show.
+- Update to `syn` v3.
