As you can see, an SPL build just compiles a few files and does not
parse the whole "Makefile tree". To avoid compiling the world in the
SPL, when I later change the Makefiles to have this "tree" logic I also
enclosed some lines into a "#ifndef CONFIG_SPL_BUILD" conditional to
avoid enlarging the SPL without reason. There is probably a way to
simplify this but for now I don't want to do it :)


Thanks,
