You need to write the relocation semantics so that it will work.  It
won't work in general.

The 64-bit MIPS ABI is an example of a processor supplement which
applies multiple relocations to a single address.  However, it does it
in a different way, by changing the reloc format.

In general it's very odd to want to add two relocatable symbols.  The
result is unlikely to be useful.
