fwiw, I like GDB_PYTHONHOME.  I'd rather not punt on this.

I'm not sure I completely understand the objections to something like
the following:

if GDB_PYTHONHOME provided
  use it
elseif PYTHONHOME provided
  use it
else
  use default
endif

That way a user can provide a PYTHONHOME and gdb will use it.   But if
it is incompatible with the python that gdb is using, they can still
have PYTHONHOME - they just need to set GDB_PYTHONHOME too.
