Only just saw this -- I was on holiday last week.

If you've got everything right, after running make in ramdisk-tiny you should
have (assuming you just added expr):

	expr.lo
	expr_stub.c
	expr_stub.o

Also, ramdiskbin.c should have been modified to invoke the entry point
_crunched_expr_stub() when argv[0] is "expr" (ramdiskbin.mk should have been
updated as well).  I vaguely remember that I may have had to remove
ramdiskbin.cache by hand to get make to DTRT.
