Merge gdbstub64.c in gdbstub.c and remove uses of
target specific TARGET_AARCH64 definition.
Small step toward single ARM/Aarch64 binary.

Are we attempting a single binary for user-only as well?

No, due to ABI constraints, right? I did a user-emulation
smoke build, no failure, did I miss something?

Well, no.  But qemu-arm does not need gdbstub64.c.
Given TARGET_AARCH64 will be set on a combined build, I'm not sure what is the fix?
