>Description:
One of my NetBSD/i386 systems is configured with the COMPAT_IBCS2 option,
but none of the COMPAT_SVR4, COMPAT_LINUX, COMPAT_FREEBSD options.
I've also managed to build my kernels without the EXEC_ELF32 option.  This
is no longer the case. During a kernel build, the following error occurred:

In file included from ../../../../kern/exec_conf.c:57:
../../../../compat/ibcs2/ibcs2_exec.h:286: syntax error before `Elf32_Ehdr'
cc1: warnings being treated as errors
../../../../compat/ibcs2/ibcs2_exec.h:286: warning: function declaration isn't a prototype
*** Error code 1

It now seems that any kernel configured with the COMPAT_IBCS2 option must
also include the EXEC_ELF32 option.  Since the IBCS2 exec file format, as
far as I know, is COFF, requiring the extra option is slightly
non-inituitive.

>How-To-Repeat:
Create a NetBSD/i386 kernel configuration file with the COMPAT_IBCS2 but
without the EXEC_ELF32 option.  make.
>Fix:
Document this dependency, or maybe make the ibcs2_elf32_probe prototype
declaration in the ibcs2_exec.h file dependent on EXEC_ELF32?
