On macOS, libbacktrace was failing to find debug information due to:
1. Debug symbols not being properly linked with dsymutil
2. Apple Clang 17.0.0 generating DWARF 5 which libbacktrace couldn't parse
In this commit we address both issues:
Debug symbol accessibility:
- Add dsymutil integration in Makefile to properly link debug symbols
- Use -fno-standalone-debug to embed debug info inline in executable
DWARF format compatibility:
- Force -gdwarf-4 instead of default DWARF 5 to avoid "DW_FORM_addrx value out of range" errors
Changelog-added: libbacktrace works with macOS
