3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: "H. Peter Anvin" <h...@linux.intel.com> commit 24ab82bd9bf18f3efc69a131d73577940941e1b7 upstream. When the relocs tool throws an error, let the error message say if it is an absolute or relative symbol. This should make it a lot more clear what action the programmer needs to take and should help us find the reason if additional symbol bugs show up. Signed-off-by: H.
