This patch changes the R_MIPS_NONE define from 0 to a magic value. This makes it possible to better detect any forbidden pre-relocation usage of BSS variables, as they are often zero'ed and then relocation is stopped too early. Additionally the error message is improved to also print the faulting address. This helps finding the root-cause for this breakage by comparing this address with the values in System.map. This patch helps a lot when working on pre-relocation code, like the Octeon DDR init code, where such variables have hit me multiple times now.
