powerpc: Fix dedotify for binutils >= 2.26
[ Upstream commit f15838e9cac8f78f0cc506529bb9d3b9fa589c1f ]
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.
