As mentioned in https://reviews.llvm.org/D67479#1667256 , * `--[no-]allow-shlib-undefined` control the diagnostic for an unresolved symbol in a shared object * `-z defs/-z undefs` control the diagnostic for an unresolved symbol in a regular object file * `--unresolved-symbols=` controls both bits. In addition, make --warn-unresolved-symbols affect --no-allow-shlib-undefined. This patch makes the behavior match GNU ld. Reviewed By: psmith Differential Revision: https://reviews.llvm.org/D91510
