[COMMITTED] bfd: fix build with --enable-targets=all in 32-bit hosts

[Jose E. Marchesi]

Sigh, of course I had to break something :/

In this case, I broke the BFD build in 32-bit hosts with
--enable-targets=all and a 32-bit default target.

Good that Sergio's buildbot for GDB catched this.
Patch below committed as obvious.

Sorry!

    bfd: fix build with --enable-targets=all in 32-bit hosts
    
    This patch avoids for bpf_elf64_le_vec to be referenced in targmatch.h
    when building a BFD without BFD64, resulting in an undefined symbol.
    This was a regression introduced along with the BPF target.
    
    bfd/ChangeLog:
    
    2019-05-23  Jose E. Marchesi  <jose.marchesi@oracle.com>
    
            * config.bfd (targ_cpu): Process bpf-*-none only if BFD64.
            * configure.ac: Set target_size=64 for bpf_elf64_le_vec and
            bpf_elf64_be_vec.
            * configure: Regenerate.
