If you type:
(gdb) show architecture 
The target architecture is set automatically (currently i386)

This is because you have no file loaded to set GDB architecture according to
it.  You can set it manually:
(gdb) set architecture i386:x86-64

GDB can support many architectures although I agree it is more a bug the
primary target is not the default.
