Use cascading-if for per-config test and install code

When generating per-config blocks in test and install scripts replace
the form

  IF()
    # config == A
  ENDIF()
  IF()
    # config == B
  ENDIF()

with

  IF()
    # config == A
  ELSEIF()
    # config == B
  ELSE()
    # no config matches
  ENDIF()

for clarity and to support the else() case cleanly.
