Since these variables are separate it means that if you want to
use both LIBOBJS and ALLOCA you should use

  program_LDADD = $(LIBOBJS) $(ALLOCA)
or 
  library_a_LIBADD = $(LIBOBJS) $(ALLOCA)

One inconsistency here is that Autoconf defines LTLIBOBJS but
not LTALLOCA.  So if you want to include alloca in a shared
library you have to define LTALLOCA as shown in the Libtool
manual (but not LTLIBOBJS).
