The point is that this just can't be done portably. You need at least
one object file, for two reasons:
(i) libtool may fail if you link only libtool archives into another
libtool archive
(ii) automake wouldn't know which compiler/linker to use for the
library you're creating. Specifying one or more source files is
supposed to give automake a clue on which languages are being used in
the sub-libraries.

Yes. It isn't portable. Some linkers just fail.
