Subject: Fix up code to be able to use the Checker.

SConstruct:
    Remove check for Checker from this SConstruct
src/arch/SConscript:
    Specific check if CheckerCPU is being used.  Not the cleanest, but works for now.
src/cpu/SConscript:
    Code to handle using the CheckerCPU a little better.  Allows -c to be used normally.
