[Bug binutils/3631] New: bfd/archive64.c is compiled unconditionally even for 32-bit targets

[uwe at NetBSD dot org]

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.
