I wouldn't!

CACHE=-C is used only on a snapshot build. These were always built
incrementally from the previous version because I judged that the risk
of a broken build was small compared to the significant time and cost
saving that the incremental build provided. A full build is easy to
achieve by simply deleting the build tree, as build-zips does an
out-of-tree. Reconfiguring requires deleting the config.cache as well.

Full release builds are built from a clean tree. The time saving is less
important there.
