Description

Optimize ebuild.sh to cache preprocessing output. Right now ebuild.sh runs preprocessing steps multiple times during the same build. It processes the same environment and produces the same output every time. This slows down the build unnecessarily. This optimization cuts build time for 50 binary packages with 16 jobs from 3m22 to 2m33 (33%). Change-Id: I72ac84cce2eb60d17736cc5f5343d4a858ec86f4 R=zmedico@chromium.org BUG= TEST=
