From c3cabf4e336c104542bb248730094747b13977b1 Mon Sep 17 00:00:00 2001 From: Sven Wegener Date: Sat, 14 Jun 2014 17:41:13 +0200 Subject: [PATCH] bare-arm, stmhal, teensy: Duplicate -nostdlib to CFLAGS As we are building with -nostdlib gcc features like the stack protector will fail linking, because the failure handlers are in gcc's internal libs. Such features are implicitly disabled during compilation when -nostdlib is used in CFLAGS too.
