automake's 1.9 NEWS entry includes:
  - Variables aumented with `+=' are now automatically flattened (i.e.,
    trailing backslashes removed) and then wrapped around 80 colummns
    (adding trailing backslashes).  In previous versions, a long series
    of
      VAR += value1
      VAR += value2
      VAR += value3
      ...
    would result in a single-line definition of VAR that could possibly
    exceed the maximum line length of some make implementations.
      
    Non-augmented variables are still output as they are defined in
    the Makefile.am.

flattening non-augmented variable assignments seems like a better
solution to the problem of too long lines.

In the mean time, maybe 

   foo_SOURCES =
   foo_SOURCES += [ long list of sources ]

might just work.
