From b695af1dfcd01bcca91c3bfc9c9a47fb62e3b27b Mon Sep 17 00:00:00 2001 From: Anthony Zhou Date: Mon, 2 Apr 2018 19:34:59 +0800 Subject: [PATCH] Tegra: remove unused libc files from makefile This patch redefines the variable LIBC_SRCS for Tegra platforms, to remove unused libc files from the list. This patch is a building block to eventually use other libc implementations in the future.
