[build] [Makefile]: Undefine _GNU_SOURCE for rglfw.c (#4732)

Browse Source 
Currently, a warning about _GNU_SOURCE being redefined is emitted when
compiling rglfw.c

In file included from rglfw.c:99:
external/glfw/src/posix_poll.c:27:9: warning: "_GNU_SOURCE" redefined
   27 | #define _GNU_SOURCE
      |         ^~~~~~~~~~~
<command-line>: note: this is the location of the previous definition

This can be avoided by not defining _GNU_SOURCE on the command line for
this file.

Defining feature test macros in source code is not really good practice
so this should probably reviewed in glfw itself, at least to maybe check
 #ifdef _GNU_SOURCE first. But for now this change will suffice.

Fixes #4725
