[U-Boot] [PATCH 2/5] kbuild: sunxi: fix build rule of sunxi-spl.bin

[Masahiro Yamada]

The build command for sunxi-spl.bin is constant, so it is pointless
to use $(call if_changed,...).  $(call cmd,...) is enough.

On the other hand, if the tools/mksunxiboot is updated, the resulted
output may be different.  Make the output image dependent on
tools/mksunxiboot.
