Remove "out" special case handling from FindEmulator

We removed the special casing of $OUT_DIR from our findleaves commands
to fix problems where $OUT_DIR was named the same as a real directory.
But now TEST_FIND_EMULATOR (and regen) is broken, since the real command
finds out/Android.mk, but the emulated version does not. Since we're
already traversing output directories that aren't called "out", just
remove the "out" special casing from the find emulator.

This raises the time to init the find emulator from 0.85s to 1.12s on my
machine with one product built. But this only happens when you're about
to read all of the makefiles anyways, not during regen. The node count
goes from 683196 to 894396.

kati

Build Status

kati is an experimental GNU make clone. The main goal of this tool is to speed-up incremental build of Android.

Currently, kati does not offer a faster build by itself. It instead converts your Makefile to a ninja file.

How to use for Android

Now AOSP has kati and ninja, so all you have to do is

% export USE_NINJA=true

All Android's build commands (m, mmm, mmma, etc.) should just work.

How to use for Android (deprecated way)

Set up kati:

% cd ~/src
% git clone https://github.com/google/kati
% cd kati
% make

Build Android:

% cd <android-directory>
% source build/envsetup.sh
% lunch <your-choice>
% ~/src/kati/m2n --kati_stats  # Use --goma if you are a Googler.
% ./ninja.sh

You need ninja in your $PATH.

More usage examples (deprecated way)

"make clean"

% ./ninja.sh -t clean

Note ./ninja.sh passes all parameters to ninja.

Build a specific target

For example, the following is equivalent to "make cts":

% ./ninja.sh cts

Or, if you know the path you want, you can do:

% ./ninja.sh out/host/linux-x86/bin/adb
