From e8e542a2168857690dc3d7a736dcc5351b0e8399 Mon Sep 17 00:00:00 2001 From: Torok Edwin Date: Wed, 15 Jul 2015 16:33:23 +0300 Subject: [PATCH] Use CCLINKFLAGS for linking all executables and shared libraries This allows packagers to set additional linker flags for executables and shared libraries created by OCaml, and for the OCaml tools themselves. OCaml code can be linked with various C stubs and C libraries that would benefit from using hardening link flags, such as -Wl,-z,relro.
