Subject: [PATCH] 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.
