Move encoded as 'or' in binutils.
A patch (http://sourceware.org/ml/binutils/2015-07/msg00376.html) submitted to binutils will be encoding move as an 'or' instruction over [d]addu in assembly and various code stubs. This patch for gdb addresses that change for the mips specific parts of gdb. gdb/ChangeLog: * mips-linux-tdep.c (mips_linux_in_dynsym_stub): Recognise 'or' as move along with [d]addu.
