engine: platform: linux: Add gettid definition for old systems

The gettid() library support was added in glibc 2.30. Earlier glibc
versions did not provide a wrapper for this system call, necessitating
the use of syscall(2).

Also, put _GNU_SOURCE definition in the guard to avoid the warning:
  ../engine/platform/linux/sys_linux.c:16: warning: "_GNU_SOURCE" redefined
   #define _GNU_SOURCE

  <command-line>: note: this is the location of the previous definition

 ## Fork features
-* HLSDK 2.4 support.
-* Crossplatform: supported x86 and ARM on Windows/Linux/BSD/Android. ([see docs for more info](Documentation/ports.md))
-* Modern compilers support: say no more to MSVC6.
-* Better multiplayer support: multiple master servers, headless dedicated server.
-* Mobility API: allows better game integration on mobile devices(vibration, touch controls)
-* Different input methods: touch, gamepad and classic mouse & keyboard.
+* Steam Half-Life (HLSDK 2.4) support.
+* Crossplatform and modern compilers support: supports Windows, Linux, BSD & Android on x86 & ARM and [many more](Documentation/ports.md).
+* Better multiplayer support: multiple master servers, headless dedicated server, voice chat and IPv6 support.
+* Multiple renderers support: OpenGL, GLESv1, GLESv2 and Software.
+* Advanced virtual filesystem: `.pk3` and `.pk3dir` support, compatibility with GoldSrc FS module, fast case-insensitivity emulation for crossplatform.
+* Mobility API: better game integration on mobile devices (vibration, touch controls)
+* Different input methods: touch and gamepad in addition to mouse & keyboard.
 * TrueType font rendering, as a part of mainui_cpp.
-* Multiple renderers support: OpenGL, GLESv1, GLESv2, Software.
-* Voice support.
-* External filesystem module like in GoldSrc engine.
-* External vgui support module.
-* PNG image format support.
-* A set of small improvements, without broken compatibility.
-
-## Planned fork features
-* Virtual Reality support and game API.
-* Vulkan renderer.
+* External VGUI support module.
+* PNG & KTX2 image format support.
+* [A set of small improvements](Documentation/), without broken compatibility.
