MKCOMPAT=yes and options COMPAT_NETBSD32 should do the trick.
Similar to our compat for sparc on sparc64 it adds a /usr/lib/oabi directory
with separate ld.elf_so and libs, so hopefully all old binaries keep
working.

A problem, however, are pkgsrc and third party (local) libraries, as
soon as you start rebuilding eabi pkgs and replace the old libs in-place.
