Another possibility is to add these lines to Makefile.am:

  # This is implicit in "make all", but is needed explicitly before other target
  # invocations.
  built-sources: $(BUILT_SOURCES)

Then people like Richard can run
  $ make built-sources specific-target
instead of
  $ make specific-target
and thus get a certain target built without the need to do "make all".

It is particularly useful for the 'make dist' target, which is required
to work _without_ preceding 'make all'. [1]
