    Makefile: Replace the way to test if a string is empty
    
    The output of command below,
    # i386-elf-nm build/cbfs/fallback/romstage_null.offenders | \
                         grep -q "" ; echo $?
    has different result on MacOS, OS X Mavericks, which outputs 0.
    On linux, it outputs 1.
    
    I assume it is misleading to search an empty string in a empty
    string. Change it to testing if the string is empty.
