   4 Subject: [PATCH] Define PTRACE_GETSIGINFO on PowerPC when not available
   5
   6 uClibc 0.9.33.2 does not define PTRACE_GETSIGINFO in PowerPC. Even
   7 though Buildroot has a uClibc patch doing that, it doesn't solve the
   8 case of external uClibc toolchain from other sources (such as
   9 Crosstool-NG). Therefore, this patch modifies Valgrind to define
  10 PTRACE_GETSIGINFO on PowerPC to the right value, when such definition
  11 is not available from the C library.
