While the ABI says AARCH64 can have .rel/.rela relocation records, rela is what is consistently used. I think we should stick to .rela in the test as well.

Aside that, is there a way to check that the yaml2obj can check for the type of relocation records thats emitted by the tool ? If so I think it would be nice to have the feature as well.
