I wrote elsewhere:

Also: buildworld is using the ELFv1 ABI in my builds.
(Both contexts are using defaults.)

This leaves me wondering if, for example, a kernel debugger
would track the kernel ABI when it is distinct from the world
ABI, given libunwind having a compile-time choice of which
ELFv? ABI to handle for r2 (TOC) use.
