>Description:
	.../src/sys/compat/aout/syscalls.master includes entries for various COMPAT_13, COMPAT_43, and other
	system calls.  This makes it impossible to build a system with (e.g.) COMPAT_AOUT and not COMPAT_13,
	due to failures of the form:

		ld -Ttext F0100000 -e start -z -X -o netbsd ${SYSTEM_OBJ} vers.o
		aout_sysent.o: Undefined symbol `_compat_13_sys_sigreturn' referenced from data segment
		*** Error code 1

		Stop.

	This combination of options is (IMHO) perfectly valid, and it's a shame not to support it.

>How-To-Repeat:
	configure a kernel with COMPAT_AOUT and not COMPAT_13.  Try to build it.  Watch it fail with
	the above error.
>Fix:
	.../src/sys/kern/syscalls.master uses the COMPAT_13 keyword, defined as a compatibility option
	in .../src/sys/kern/syscalls.conf to selectively include/exclude NetBSD-1.3 compatibility
	functions.  Probably, this should be added to .../src/sys/compat/aout/syscalls.{conf,master},
	but I'm not sure that it's as simple as that.
