Fixes PR48071 * The Rust compiler produces SHF_ALLOC `.debug_gdb_scripts` (which normally does not have the flag) * `.debug_gdb_scripts` sections are removed from `inputSections` due to --strip-debug/--strip-all * When processing --gc-sections, pieces of a SHF_MERGE section can be marked live separately `=>` segfault when marking liveness of a `.debug_gdb_scripts` which is not split into pieces (because it is not in `inputSections`) This patch circumvents the problem by not treating SHF_ALLOC ".debug*" as debug sections (to prevent --strip-debug's stripping) (which is still useful on its own).
