Cross building for the same sized longs, maybe. But _all_ platforms,
I doubt it! I just tried building binutils on FreeBSD/i386 with both
elf32 and elf64. From what I can see from the compiled warnings (and
the resulting assertions), the elf64 code is not intended for use on
any architecture where sizeof(long) < 8.

Now, building elf32 and elf64 on FreeBSD/Alpha is more realistic.
But how much GNU relies on host variables sized the same way as
target variables, I'm not sure. If objdump on alpha can disassemble
an i386 aout object, I'll concede that it works. Anyone care to
place bets? 8-)
