i'd keep these lines, avoiding the multiple s+2 expressions
down the road.

my main concern is making sure we'r not blowing the stack
with this change on archs with small 4k stacks like 32bit arm.

just need to checks...

also:

> +			ehdr = (void*)buf;

not sure if that will yield properly aligned ehdr pointer as
buf is just char[]. i think that was the reason it was a union
before.

otherwise looks ok.
