Fine with me. It's always difficult to gauge the right level of detail in
these dump tests. I certainly don't want to be perpetually updating them.

Thanks. I'll give it 48hrs to see if anyone shows interest in this feature
as per Maciej's request and then commit if not. I'm also happy to use
Maciej's proposed DT_MIPS_RLD_MAP_REL as the name so will switch to that.
