As in
  libfoo_la_SOURCES = foo.c @substed@
  libfoo_la_LIBTOOLFLAGS = --tag=disable-static

and 'AC_SUBST([substed], [...])'?  Should work if you add the list of
possible sources in EXTRA_libfoo_la_SOURCES, I believe.  Should also
work for conditional sources:
  if COND
  libfoo_la_SOURCES += baz.c

That is another possibility, but of course limits what can be built in
