In that circumstance, you're mostly going to be distributing firmware
blobs. I'd probably rip the relevant code out of boost (perhaps set up
a script to do this), drop it somewhere in my project folders, and tie
it in with my build system. Respecting, of course, the license
requirements of boost.

It's unfortunate that boost's build system isn't modular, and
especially that it won't parallelize. I'll probably look at it at some
point to figure out if I know enough to rewrite it in autotools. I
could totally see a "--with-this-module=yes" per-module, as opposed to
an "--enable-all" for those users who don't know which parts they do
or don't need.

It's something that needs to be done. The question is who's going to
have the time and inclination.
