We want to ignore any export stub remnants here.
The value returned is used in two different ways:
1. To find a function's caller.
2. To change the return address for a function.
This function handles most instances of case 1; however, it will
fail if there are two levels of stubs to execute on the return
path. The only way I believe that can happen is if the return value
needs a parameter relocation, which never happens for C code.
This function handles most instances of case 2; however, it will
fail if we did not originally have stub code on the return path
but will need code on the new return path. This can happen if
the caller & callee are both in the main program, but the new
return location is in a shared library.
To handle this correctly we need to set the return pointer at
frame-20 to point to a return stub frame-24 to point to the
location we wish to return to. */
