[PATCH] D96914: [ELF] Add -z start-stop-gc to let __start_/__stop_ not retain C identifier name sections

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

@tstellar I forgot one point the said breakage (for some software not working with GNU ld<2015-10) requires `-fdata-sections -Wl,--gc-sections`, which isn't common among distros.
The symptom is obvious: `error: undefined symbol: __start_XXX`. The fix is straightforward: remove `-Wl,--gc-sections` or use `-z nostart-stop-gc`.
So now I am not even sure it makes sense to revert it for release/13.x.

I try to be impartial and try to think of many factors. That is it.
