Strange Makefile rule

I do not have cross compile environment but I'm curious how the
Makefile rule works:

linux-next]$ cat drivers/net/ethernet/arc/Makefile

obj-$(CONFIG_ARC_EMAC) += arc_emac.o

There is no file named arc_emac.h and arc_emac.c at
drivers/net/ethernet/arc, so what does that line do?
