I believe Jason Thorpe added 'BOOTSTRAP_ELF' as an option to assist this
transition.  I believe you would set it to YES in /etc/mk.conf, and rebuild
the toolchain.  Perhaps even a 'make build' would work.  This should generate
a toolchain that can build ELF, but defaults to AOUT. (correct me if I am
wrong Jason)  Once this is completed, you can add the 'OBJECT_FMT=ELF' to
/etc/mk.conf and build native ELF binaries.

I _think_ the sequence would be something like this:
(somewhere in this should be a DESTDIR=/some/safe/place??)
- set BOOTSTRAP_ELF=YES in /etc/mk.conf
- build toolchain (src/gnu/usr.bin/????) & lib/csu & libbfd?
- set OBJECT_FMT=ELF in /etc/mk.conf
- set LDSTATIC=-static in /etc/mk.conf (optional? But a good idea I think)
- start building... :)

I would suggest building everything statically first, to allow you to have
the AOUT binaries/libraries still working as you test out ELF binaries.
Once you have a working ELF system, you can build the libraries, and verify
them, then go for it with a make build. :)

Your other option is to just load an ELF snapshot.  I plan on making
most(*) of one available shortly via my webpage, or on ftp.netbsd.org
if they let me.

(*) "most of" being base/comp/kern/text at least, depending on the quota
on my webpage. :)

Would you be able to test a snapshot of -current from this week?
