>Description:
Each architecture has its own little language of relocation semantics in the ELF ABI.

ld.elf_so tries to faithfully implement these little languages for each architecture.  But sometimes it has bugs, or the language gets extended.

We need to record (and archive) references to the processor supplements to the ELF ABI which define the relocation semantics.
>How-To-Repeat:
code inspection
>Fix:
Yes, please!
