Currently, Kati is the only one that is respecting OUT_DIR_COMMON_BASE, causing the build to fail when ninja tries to match up the Soong and Kati ninja files. The soong_ui.bash script change is necessary to move the microfactory built outputs to the correct location. The config.go change takes care of setting OUT_DIR in the environment of every subprocess, so that we could remove the OUT_DIR_COMMON_BASE handling from Make once the USE_SOONG_UI=false path goes away. Bug: 35929763 Test: m -j blueprint_tools Test: OUT_DIR=... m -j blueprint_tools Test: OUT_DIR_COMMON_BASE=... m -j blueprint_tools Change-Id: I4184f2b4392d32c5bea51e51162a48df0e5c90d5
