Off-hand, no, I don't know why it happened.  At a low level, it means
that you compiled something with -fPIC, and gcc generated a function
call to some symbol, and by link time that symbol was local.  That
could be because it was a static function in the original file, which
might indicate a gcc bug, or it could be because you set the
visibility at compile time, or used -Bsymbolic or a version script or
something like that at link time.

I would advice simply using binutils 2.20.  If that is impossible for
some reason, then you need to find out why the linker thinks that the
symbol is local, and why the compiler generated a PLTREL24 reloc for
the symbol.
