Do not limit threads upon calling legacy GNU make

Limiting legacy GNU make and making ninja run faster might sound ok,
but on Android, huge amount of time is still being spent on GNU make.

For example :
limiting the threads to half causes huge slowdown to inline kernel builds.

Unlock this limit and allow GNU make to fully utilize all CPU cores.

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
