* simple_game: Configure Make and makefile for Linux environments

* simple_game: Fix build issues on Android plaform with Linux HOST

The Makefile.Android.linux file was out of date with the rest of the
project, so this commit updates the paths, as well as leaving some as
optional, if it is already configured as an environment variable.

In addition, it corrects the build error related to static raylib:
the makefile was trying to generate libmain.so using the path of the
NDK libraries, instead of using those of the Android system, which
resulted in crashes in the generated apk.

For uploading a apk to Google Play a minimun of 25 years (9125 days) is needed for the validity of the key.

* Create makefile for building android app on osx

This makefile can work on macos to build android app

* Update and rename Makefile.macos.android to Makefile.Android.macos

Rename the makefile for android macos.

* Update Makefile.Android.macos

replace the user specific folder with env var $HOME

* new linux makefile for Android portages

* Revert "projects: CMake: bump up minimal raylib version (#983)"

This reverts commit 82306af111.

* new PR for upstream

* for Raysan

Now it's required on Windows if not using a busy wait loop

raylib resource data file for Windows platform (containing raylib icon and metadata for executable file) has been renamed to a more consistent name: raylib.rc.data

Also required to work with tcc compiler.

From 2019 64bit support will be mandatory to publish an Android app.
Google plans to require that new apps target Oreo (API level 26) in
August of 2018.

Currently, if:
* GCC doesn't supports -no-pie: Build error
* GCC supports -no-pie
    * GCC is not configured with --enable-default-pie: No-op
    * GCC is configured with --enable-default-pie:
            Slightly worse performance because we still generate -fpie code
            (-pie affects linker, -fpie affects compiler)

So instead of probing for existence of -fno-pie -no-pie, remove it altogether.

Fixes #540: Build breakage on Debian 8 with gcc 4.9.

Review raylib_icon resource

Removed OpenAL and GLFW3 dependencies on building.
Reviewed platforms and flags

Inspired by #504.
Instead of requiring the user to do PLATFORM_ANDROID #ifdefery,
have the android_main entry point exported by raylib and call
the user-defined main. This way many games could (in theory)
run unmodified on Android and elsewhere.

This is untested!

- Renamed VERSION to RAYLIB_VERSION
- Renamed API_VERSION to RAYLIB_API_VERSION
- Renamed RAYLIB_RELEASE to RAYLIB_RELEASE_PATH
- Support Web Assembly compilation on PLATFORM_WEB

- Removed useless templates
- Reviewed all Makefiles
- Rework some code for Android support
- Added resources to advance template

I've added .PHONY targets and fixed "clean" recipe.
