3Subject: Don't check shared/export_dynamic/ref_dynamic for type mismatch
4X-Git-Tag: hjl/linux/release/2.24.51.0.3~1^2~8^2~22

7Don't check shared/export_dynamic/ref_dynamic for type mismatch
8
9There is nothing linker can do when a type mismatched default definition
10are made dynamic by info->shared, info->export_dynamic or h->ref_dynamic.
11But we do want to avoid exporting it when building PIE. Let's remove
12those checks.
