Subject[PATCH v2 3/4] net: wan: wanxl: refactor the firmware rebuild rule
Date
Split the big recipe into 3 stages, compile, link, and hexdump.

After this commit, the build log with CONFIG_WANXL_BUILD_FIRMWARE
will look like this:

M68KAS drivers/net/wan/wanxlfw.o
M68KLD drivers/net/wan/wanxlfw.bin
BLDFW drivers/net/wan/wanxlfw.inc
CC [M] drivers/net/wan/wanxl.o
