From 1239610e223358d31bd9126f3bc5928deeba5d5f Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 12 Oct 2014 19:27:14 +0200 Subject: [PATCH] valgrind: add patch to fix build on PowerPC uClibc uClibc on PowerPC forgot to define some PTRACE_* definitions. Even though the Buildroot uClibc package has a fix for this, it doesn't fix external uClibc toolchains that are not patched. Therefore this commit adds a patch to Valgrind to workaround the problem by defining PTRACE_GETSIGINFO to the appropriate value on PowerPC when it's not defined by the C library.
