$NetBSD: patch-Makerules,v 1.2 2025/08/29 09:17:06 leot Exp $

- Handle the various operating systems in the same way avoiding hardcoding
- Avoid to use objcopy by setting HAVE_OBJCOPY to no (if `yes', and with
  `USE_TOOLS+= objcopy' the objcopy-ing fails as follow:
    OBJCOPY build/release/resources/fonts/urw/Dingbats.cff.o
    build/release/resources/fonts/urw/Dingbats.cff.o:1: warning: NUL character seen; rest of line ignored
    build/release/resources/fonts/urw/Dingbats.cff.o:1: *** missing separator.  Stop.
  (also for other fonts)).  This needs to be investigated further.
- Avoid internal version of freeglut and try to pick it up via pkg-config and
  set SYS_GLUT_{CFLAGS,LIBS} accordingly.
