These makefiles give me headaches as well. :)

While there are no entries at the end of the file
# Clocks
clock_60hz: clock.asm
	$(AS) $(AFLAGS) $(ASOUT)$@ $< -DPwrLnFrq=60

clock_50hz: clock.asm
	$(AS) $(AFLAGS) $(ASOUT)$@ $< -DPwrLnFrq=50

clock2_cloud9: clock2_ds1315.asm
	$(AS) $(AFLAGS) $(ASOUT)$@ $< -DCLOUD9=1

clock2_bnb: clock2_ds1315.asm
	$(AS) $(AFLAGS) $(ASOUT)$@ $< -DBNB=1
for some of the clocks, there are entries towards the beginning of the makefile.

CLOCKELIM       = -DRTCElim=1
CLOCKDISTO2     = -DRTCDsto2=1
CLOCKDISTO4     = -DRTCDsto4=1
CLOCKBNB        = -DRTCBB=1
CLOCKSMART      = -DRTCSmart=1 -DMPIFlag=1
CLOCKHARRIS     = -DRTCHarrs=1
CLOCKCLOUD9     = -DRTCCloud9=1
CLOCKSOFT       = -DRTCSoft=1
CLOCKMESSEMU    = -DRTCMessEmu=1
CLOCKJVEMU      = -DRTCJVEmu=1

CLOCKS          = clock_60hz clock_50hz \
		clock2_elim clock2_disto2 clock2_disto4 clock2_bnb \
		clock2_smart clock2_harris clock2_cloud9 clock2_soft \
		clock2_jvemu clock2_messemu clock2_dw

So, all the necessary clocks will be built. What has not been done or needed in 
CLOCKSMART is a conditional based on the MPIFlag. That clock2 will always search 
as if an MPI were present.
