    BUILD: add .config dependency to $(obj)/config.h
    
    Without it, replacing .config by a different config leads to all
    kinds of annoying build errors like the following:
    $ cp config-t60p .config
    $ make
    Makefile:235: warning: overriding commands for target `build/cpu/x86/name/name.ramstage.o'
    Makefile:235: warning: ignoring old commands for target `build/cpu/x86/name/name.ramstage.o'
        ROMCC      mainboard/lenovo/t60/bootblock.inc
        GEN        bootblock/bootblock.S
        CC         mainboard/lenovo/t60/bootblock.s
        CC         mainboard/lenovo/t60/bootblock.o
        LINK       bootblock.elf
        OBJCOPY    coreboot.bootblock
        CC         lib/ramtest.romstage.o
    cc1: warnings being treated as errors
