System: NetBSD night-rest.duskware.de 7.99.26 NetBSD 7.99.26 (GENERIC) #147: Wed Feb 3 14:56:31 CET 2016 martin%seven-days-to-the-wolves.aprisoft.de@localhost:/ssd/src/sys/arch/shark/compile/GENERIC shark
Architecture: earmv4
Machine: shark
>Description:

PR port-arm/50760 shows a problem with relocating the exec_elf32 module
on shark, however, it also demonstrates that the kernel even tries to
load this module, which is plain wrong:

NAME                    CLASS    SOURCE   FLAG REFS  SIZE    REQUIRES 
exec_elf32              exec     builtin  -    2     -       -


>How-To-Repeat:

On a machine with builtin exec_elf32 module run:
cd /usr/tests/lib/libc/gen/posix_spawn/ && atf-run t_spawn

>Fix:
n/a
