This rather looks like a qemu upstream issue. But as no qemu arch comes
without gdbstub support and this switch is always true, no one noticed it.
But why not fixing the core issue, ie. adding gdbstub support, or at
least some intermediate dummy functions until qemu gains full ia64
support? That would also allow to clean up the CONFIG_GDBSTUB #ifdef'ery
from upstream. And it would be the first step towards kvm guest
debugging support for ia64.
