Peter,
The commit short message needs to be corrected to the binutils: ...
format please.
I will test this version in MUT.
Thanks
Sau!

The ar and strings utilities are provided as alternatives, but
the rest of binutils is being done with binutils-symlinks. This
has the side effect that if you want "as", and you install
binutils-symlinks to get it, you don't get "ar" from it, because
it's not in the symlinks package.
Solution: Use the same mechanisms for everything, putting
everything in ALTERNATIVES, so installing binutils on a target
produces the expected behavior of having the various utilities in place.
(We do this only for class-target, though.)
Issues: The "embedspu" and "ld.gold" binaries may or may not exist,
but the determination of whether to list them as alternatives is
being made before the point at which we can easily check for them,
so that can produce warnings.
