net: wan: wanxl: refactor the firmware rebuild rule
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 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
