make.base
      Add rule for ldscript.ld
printk.h
      Fix typo it should be printk_alert not printk_alart...
NLBConfig.py
      - Removed some dead code
      - Modified mainboardinit and ldscript to act like my recently modified
        object command and take as a suffix a config option that must be
        set to one for them to work.
      - No longer generate ldscript.ld instead generate ldoptions and
        the variable LDSUBSCRIPTS-1.
