With USE_GOMA, the path to gomacc in $GOMA_DIR or $HOME/goma will be appended to CC_WRAPPER and CXX_WRAPPER. Note this works only with USE_NINJA. Unlike ninja, GNU make cannot change the parallelism depending on targets. Specifying -j500 to GNU make would mean you may run 500 local jobs in parallel, but with -j32 goma will just slow down the build. Change-Id: I0f571454fd2a5b525ee29b445f7ab8715927ca00
