4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Andreas Schwab <[email protected]> commit f15838e9cac8f78f0cc506529bb9d3b9fa589c1f upstream. Since binutils 2.26 BFD is doing suffix merging on STRTAB sections. But dedotify modifies the symbol names in place, which can also modify unrelated symbols with a name that matches a suffix of a dotted name. To remove the leading dot of a symbol name we can just increment the pointer into the STRTAB section instead. Backport to all stables to avoid breakage when people update their binutils - mpe.
