When compiled for platforms other than __i386__ or __x86_64__:

drivers/net/ethernet/dec/tulip/tulip_core.c: In function ‘tulip_init_one’:
drivers/net/ethernet/dec/tulip/tulip_core.c:1296:13: warning: variable ‘last_irq’ set but not used [-Wunused-but-set-variable]
 1296 |  static int last_irq;

Add more #if defined() to totally remove the code when not needed.
