Not that I'm aware of. I had expected interest when I posted my efforts
with link-time-optimisation, but nothing went anywhere. So from here, I
suggest you either dig into the build system (patches most welcome!), or
contract a Samba development shop[1] to look into this for you. If you
do dig into the build system, look at how the MIT KDC and without-ad-dc
options are implemented, using the enabled flag on each subsystem.

that isn't reasonable with modern, larger flash drives and RAM.

Some
time ago I use this to solve a similar problem: 

"the Ultimate Packer
for eXecutables"

Hope it helps.
