I have only a binary for an Evolving Algebra (ASM) tool:

(groo, 24) ~/ASM-WB/bin>uname -spr
NetBSD 1.4 i386
(groo, 25) ~/ASM-WB/bin>file ./asm-wb

(groo, 27) ~/ASM-WB/bin>kdump

  3006 asm-wb   RET   write 42/0x2a
  3006 asm-wb   CALL  exit(0x80)
(groo, 28) ~/ASM-WB/bin>

I assume that `asm-wb' is an a.out executable?  In /emul/linux/lib, installed
from suse_*, we have:

-rwxr-xr-x  1 root  wheel  0 Apr 10 21:45 /emul/linux/lib/ld.so

(No kidding that's an Exec format error! ;-) )

Any chance of emulating this binary?

	/emul/linux/usr/i486-linuxaout

is essentially empty (directories for bin, lib and include exist).

Forgive my Linux a.out emulation stupidity.  Everything Linux of mine is ELF.
