* 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The Makefile.Android.linux file was out of date with the rest of the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.

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.

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

- 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.

I've renamed all makefile files to "Makefile" because they appear in the first files.

I've added "-ldl" library, it's necessary to compile the project.

I've cleaned the GNU/Linux compilation, now you can compile without useless parameters.

If you have raylib on standard directories ("/usr/local/include/raylib/raylib.h" for the header and "/usr/local/lib/libraylib.a" for raylib library) you can compile without edit the makefile.

I've changed all default target names with 'all'. Here there is the explanation: <https://www.gnu.org/prep/standards/standards.html#Standard-Targets>.

Now support multiple platforms

Some basic to advance templates are provided to be use as base code for
new games

This is a huge update. Check CHANGELOG for details
