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.

Define PTRACE_GETSIGINFO on PowerPC when not available



uClibc 0.9.33.2 does not define PTRACE_GETSIGINFO in PowerPC. Even

though Buildroot has a uClibc patch doing that, it doesn't solve the

case of external uClibc toolchain from other sources (such as

Crosstool-NG). Therefore, this patch modifies Valgrind to define

PTRACE_GETSIGINFO on PowerPC to the right value, when such definition

is not available from the C library.
