Given the nature of these changes I think you're making a lot of unnecessary
work for yourself.  But if you prefer to do it this way, feel free.

I've already stated that I think the solution to this problem is to force
whatever flags we need to make the stage1 & stage2 compilers generate
compatible code.

If the stage1 & stage2 compilers are not  link compatible, then you have a
cross compiler and therefore should not be building stage2 to begin with!
