bfd/archive64.c is always compiled even for 32-bit targets that don't need it.
configure sets bfd_libs to either
bfd_libs='$(BFD64_LIBS) $(BFD32_LIBS)'
or
bfd_libs='$(BFD32_LIBS)'
and that's propagated to the bfd/Makefile as
BFD_LIBS = @bfd_libs@
but this make variable seems unused.
I'm not very familair with automake, but I think that instead
libbfd_la_SOURCES = $(BFD32_LIBS_CFILES) $(BFD64_LIBS_CFILES)
(where BFD64_LIBS_CFILES = archive64.c) is used to determine which files
to compile, and so archive64.c is always picked up.
Found this with 2.16.1 and confirmed on HEAD. This bug has been about since
automake'ification, I guess.
