ASLR is automatically disabled by GDB 7, but that and "set disable-randomization on" seems to work only on Linux. For QEMU, it could be possible to make a workaround (for example a new flag for configure which disables ASLR). I think ASLR enabled should be the default.
You can piggyback that onto --enable-pie/--disable-pie.Enabling PIE by default would be a good thing in general for security, BTW, even for softmmu targets.
