A different approach to fixing this bug

I was playing with this one today, before I found your bugzilla Andrew.  It has
been regression tested on x86_64, fixes the loss of section attributes, and
builds a 3.16 x86_64 defconfig kernel - haven't checked if it boots yet..

Adds a fix for C++ which has the same problem as C.  (The s/olddecl/newdecl/
lines are because "if (TREE_CODE (newdecl) == FUNCTION_DECL) ... else switch
(TREE_CODE (olddecl))" looks horrible.  Cosmetic really since we exit the
function before this code if TREE_CODE (newdecl) != TREE_CODE (olddecl).)
