Exactly what I intended doing when I found a spare moment.  x86 has
qnx to contend with as well.

Of course, the bloat only happens when you enable multiple bfd
targets, and I have a nagging suspicion that certain operations
(*) might bomb with "File format is ambiguous" if you provide
two bfd vectors.

*) Like "objcopy -O binary blah.o blah.bin".  Hmm, here's an
example:

$ .../all/binutils/objcopy -O binary powerpc-linux/libiberty/hex.o blah.bin
all/binutils/objcopy: powerpc-linux/libiberty/hex.o: File format not recognized
$ .../x86/binutils/objcopy -O binary powerpc-linux/libiberty/hex.o blah.bin
$ 

The "all" objcopy is --target=i686-linux --enable-targets=all,
while the "x86" objcopy is --target=i686-linux
--enable-targets=i686-linuxaout,i686-coff,hppa-linux,powerpc-linux

The first case fails because we're reading a non-default object which
matches multiple powerpc targets, while the second case works because
we only have one matching target.  Not that I think this is
particularly worrying.  I'm just illustrating the point that providing
two targets may not be desirable in all situations.

Gack, and that's a terrible error message from objcopy.  Fixing..
