Oops!! That was a copy paste error. It was intended to be:
+LIBS-$(CONFIG_SYS_SPL_NAND_SUPPORT) += nand/libnand.o
+LIBS-$(CONFIG_SYS_SPL_ONENAND_SUPPORT) += onenand/libonenand.o

The top-level Makefile doesn't include any source files by itself.
All SPL content comes from one or more of libraries. So, there
will be at least one library defined, I believe(unless there
is an error, of course).
