valgrind: add patch to fix build on PowerPC uClibc
PATCH 1/1 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.
