It would not affect this at all.

It is exactly as hard or as easy to debug a core file from something
compiled with
cc -o bsd obj1.o obj2.o obj3.o
as with something compiled with
cc -o bsd obj2.o obj3.o obj1.o

The relinking is done so that exploit code that knows how to find an
address inside obj1 will not be able to jump into obj2 by taking the
obj1 address and adding 83743 bytes to it and expect to land at a
certain place in obj2. In the first case it would work, in the second
it would not.
