arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings work
As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.
