For a host environment like DJGPP, I agree with the recommendation for
ELF crash dumps.  

However, I wanted to mention that for embedded environments, it may be
better to use a custom crash dump format.  One requirement I had was I
had to write dumps to streaming media (in other words, no seeks).  I
suspect I could have written ELF dumps by doing two passes over the
system (one to compute the offsets, another to write the dump), it was
simpler to use a format designed for streaming from the get go.
