Is it really?  My understanding is that it is comparable to sparc
vs. sparc64.  Isn't it possiblle to execute normal 32-bit i386 code on
the x86_64?  In that case, you'd probably want to have a GDB that can
handle both.  The only way to be able to accomplish that in the near
future is seeing them as different variants of the same architecture.
In that case you should leave the files where they are now.
Incidentally that's what GCC does.

If you want these targets to become really seperate, we should
consider doing a repository copy of the files to preserve their
history.
