I think this feature would be fine if it was optional, not turned on by 
default, and documented with warning about unexpected build or option 
changes.

We may want to look at FreeBSD for example:

/var/db/ports/${portname}/options  -- store your options used by builds

make showconfig -- show them

make rmconfig -- remove them

This assumes you use same system to do builds.

FreeBSD also provides menus to select options during the build -- but I 
don't like that "interactive" feature myself.
