From 3dbaad0a1f27b96462541e1189efe37ffa913e9a Mon Sep 17 00:00:00 2001 From: Albert Ou Date: Tue, 13 Dec 2016 15:05:19 -0800 Subject: Refactor libc stubs into libwrap The --wrap feature of GNU ld supports a cleaner framework for linking in alternative implementations of libc functions without cpp hacks.
