Quickest way to rebuild if you just change PLIST

[Mayuresh <mayuresh%acm.org@localhost>]

Sometimes PLIST errors are realized after spending a lot of time to build
a large package. Doing a make clean and starting all over just because of
PLIST change sounds daunting for large packages.

Is there a quick way, such as manually changing files under work area so
that fresh build time can be saved?
