At this moment, physac is an external unmaintained library, better move out of raylib.

rcore_desktop_sdl.c was not present in the list of prerequisites this
patch changes them to use a wildcard, so any other platforms added in
future will be tracked properly

Currently doing the following:
```
make
touch rcore_desktop.c
make
```

Will not result in rcore.o getting compiled again, despite that
rcore_desktop.c has changed

This reverts commit 70286c7cdc.

Working from wsl and compiling for windows this change makes it much easier to compile a static library for windows on arm.
To compile a static library for windows on arm:

```
make PLATFORM=PLATFORM_DESKTOP TARGET_OS=WINDOWS CROSS_CC=/llvm/bin/aarch64-w64-mingw32-gcc CROSS_AR=/llvm/bin/aarch64-w64-mingw32-ar
```

This does not work to compile a shared library yet, only static.

* Continuation of support for ES3/WebGL2

* GetTouchPointState()

* Amends to the WebGL2 PR

* added cross compilation options for DRM

* fixed identation

Reasons to NOT define `_GNU_SOURCE`:

 - access to lots of nonstandard GNU/Linux extension functions
 - access to traditional functions which were omitted from the POSIX standard (often for good reason, such as being replaced with better alternatives, or being tied to particular legacy implementations)
 - access to low-level functions that cannot be portable, but that you sometimes need for implementing system utilities like mount, ifconfig, etc.
 - broken behavior for lots of POSIX-specified functions, where the GNU folks disagreed with the standards committee on how the functions should behave and decided to do their own thing.

This linkage is only required for arm 32bit but I don't know how to detect that specific architecture in the Makefile...

* Fix Undefined Symbol `_ftelli64`

* Add files via upload

* Update raylib.h

* Update raylib.h

* test if clang supports multiple targets

* didnt work, so trying lipo to join separate targets together

* add CUSTOM_LDFLAGS to try to fix arm64 mac dynamic build

* fix sym links

* try again to fix sym links

* auto extract raylib version numbers from makefile

* fix macos missing gnu grep

* dont use custom name for raylib dlls

* Fixed an issue when using raygui and physac on unix systems
hash "#" is single-line comment character in bash so echo ignores #include and #define

* tab fix

* Properly fix make clean under sh.exe

* Ensure make clean works properly under Windows if RAYLIB_RELEASE_PATH is modified

This reverts commit ab47c6401e.

Tested on the following environments:
 - w64devkit.exe
 - Windows 10 cmd
 - Notepad++ NppExec console

GNU make on Windows first tries to find sh.exe on the path,
and will execute build rules using it if it is present.
The make clean target uses the builtin cmd.exe command del, which
won't work under sh.exe

The reason this is not done for the entire Makefile is because it would
break cross-compilation of raylib.
