>Description:
	
	Add recognition of a VAX target to cross/binutils.
>How-To-Repeat:
	Want a cross-assembler to VAX.
>Fix:
	

Here are some changes for the cross/binutils package, to make it recognise
a VAX target.

There are some complications with these patches, I think, and I haven't
figured out the cross building system well enough to provide
satisfactory answers.

- There is already another copy of libbfd and libopcodes in the system
  sources: in src/gnu/dist. There seems to be no synchronisation between
  the cross-binutils and those sources. In fact, I basically took most
  changes here from the src/gnu/dist directory.
- These patches also need to be applied to the binutils that are
  unpacked in the egcs source tree when building the crosscompiler
  (later on, from the cross/vax-netbsd package). This is the third copy
  of binutils stuff. This seems rather inelegant.
- The third copy of binutils stuff seems to be configured, but not
  compiled?
- After changing .am or .in files, one needs to run automake or
  autoconfig. The versions I have of these tools differ from those
  orginally used. The amount of diffs for this is very great, and I left
  them out here.
- I took a file from the first copy of binutils to use here.
    binutils-2.9.1/opcodes/vax-dis.c <- src/gnu/dist/opcodes/vax-dis.c
- Somehow the shared libraries are not build, only the static libraries.
  This causes problems later when building the cross-gcc.
  But this may be a host-specific issue, not target-specific.

A patch to the package:
