[C++] Don't sort find/ls results

These should only be sorted if explicitly requested, otherwise
make-built binaries may be different from kati-built binaries.

This resolves some binary-diff issues for Android between libc.a built
with make vs kati/ninja. To be the same across multiple
checkouts/machines, we should probably switch android to sorting these
results, but then the kati ninja support will stop working.

kati

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

How to use for Android

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

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

"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

Specify the number of default jobs used by ninja

% ~/src/kati/m2n -j10
% ./ninja.sh

Or

% ./ninja.sh -j10

Note the latter kills the parallelism of goma.
