As far as I understood from the Kconfig help text, this build rule is used to rebuild the driver firmware, which runs on the QUICC, m68k-based Motorola 68360. The firmware source, wanxlfw.S, is currently compiled by the combo of $(CPP) and $(AS68K). This is not what we usually do for compiling *.S files. In fact, this is the only user of $(AS) in the kernel build. Moreover, $(CPP) is not likely to be a m68k tool because wanxl.c is a PCI driver, but CONFIG_M68K does not select CONFIG_HAVE_PCI. Instead of combining $(CPP) and (AS) from different tool sets, using single $(CC68K) seems simpler, and saner. After this commit, the firmware rebuild will require cc68k instead of as68k. I do not know how many people care about this, though. I do not have cc68k/ld68k in hand, but I was able to build it by using the kernel.org m68k toolchain.
