>Originator:     Martin Husemann
>Release:        NetBSD 8.99.12
>Organization:
The NetBSD Foundation, Inc.
>Environment:
System: NetBSD thirdstage.duskware.de 8.99.12 NetBSD 8.99.12 (MODULAR) #59: Tue Jan 30 13:52:49 CET 2018 martin@thirdstage.duskware.de:/usr/src/sys/arch/sparc64/compile/MODULAR sparc64
Architecture: sparc64
Machine: sparc64
>Description:

Between Jan 30 and today "something" broke the 32bit compat ld.elf_so
on sparc64, although no relevant changes happened to src/libexec/ld.elf_so.

This breaks all atf tests running 32bit compat binaries.

Replacing /libexec/ld.elf_so-sparc with an older version fixes the fallout.

>How-To-Repeat:

Compile the typical hello.c with -m32 (but w/o -static) and try to run
the exectutable. It dies in _sysctl() when the caller meant to call
something else (and thus with completely bogus arguments).

>Fix:
n/a
