Rollup merge of #85772 - luqmana:ignored-metadata, r=petrochenkov
Preserve metadata w/ Solaris-like linkers. #84468 moved the `-zignore` linker flag from the `gc_sections` method to `add_as_needed` which is more accurate but Solaris-style linkers will also end up removing an unreferenced ELF sections [1]. This had the unfortunate side effect of causing the `.rustc` section (which has the metada) to be removed which could cause issues when trying to link against the resulting crates or use proc macros. Since the `-zignore` is positional, we fix this by moving the metadata objects to before the flag. [1] Specifically a section is considered unreferenced if: * The section is allocatable * No other sections bind to (relocate) to this section * The section provides no global symbols https://docs.oracle.com/cd/E19683-01/817-3677/6mj8mbtbs/index.html#chapter4-19
