[PATCH v3 16/27] compiler: Option to add PROVIDE_HIDDEN replacement for weak symbols
..._PROVIDE_HIDDEN
+ bool
+ help
+ Generate linker script PROVIDE_HIDDEN entries for all weak symbols. It
+ allows to prevent non-pie code being replaced by the linker if the
+ emit-relocs option is used instead of pie (useful for x86_64 pie).
