System: NetBSD speedy.whooppee.com 9.99.46 NetBSD 9.99.46 (SPEEDY 2020-02-07 16:26:35 UTC) #1: Fri Feb 7 19:37:58 UTC 2020 paul@speedy.whooppee.com:/build/netbsd-local/obj/amd64/sys/arch/amd64/compile/SPEEDY amd64
Architecture: x86_64
Machine: amd64
>Description:
	Existing built-in compat_netbsd32 code doesn't handle a.out
	images.

	Built-in compat_netbsd32 module is built _without_ having
	EXEC_AOUT defined, so the a.out execsw doesn't get defined,
	and check_exec() doesn't find a match.  It therefore returns
	ENOEXEC

>How-To-Repeat:
	Build a stock GENERIC kernel and try to run a static image
	from NetBSD-i386 version 0.9

>Fix:
