Add the ppc64le patch from Fedora llvm 3.4

Doesn't actually change anything since lldb requires gcc 4.6 and is disabled on EL6

+
+[PPC64LE] ELFv2 ABI updates for the .opd section
+The PPC64 Little Endian (PPC64LE) target supports the ELFv2 ABI, and as
+such, does not have a ".opd" section.  This is keyed off a _CALL_ELF=2
+macro check.
+
+The CALL_ELF check is not clearly documented at this time.  The basis
+for usage in this patch is from the gcc thread here:
+http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01144.html
+
+> Adding comment from Uli:
+Looks good to me.  I think the old-style JIT doesn't really work
+anyway for 64-bit, but at least with this patch LLVM will compile
+and link again on a ppc64le host ...
