Parallel build of collects is now the default option.

You can change the setup options by specify an environment variable to 
make install

; only use one processor
SETUP_OPTIONS="-j 1" make install
; use three processors don't build docs
SETUP_OPTIONS="-j 1 -D" make install

raco setup -u now means uniprocessor.  It will build collects using the 
original serial process (before parallel build was committed)
