[PATCH] cross-compilation for binutils.

Jakub, please could we apply this patch to the binutils specfile?
It provides an optional %{binutils_target} macro which, when defined,
will generate a cross-binutils package. But when it's _not_ defined, as
it won't be for your builds or in the build system, it just builds a
native binutils as before.
This will make it easier for people to build cross-binutils based
exactly on the the Fedora binutils packages.
We'll then want to look at how best to get a set of cross-binutils
packages into Fedora, without adversely affecting your workflow on the
native binutils.
The naïve approach is just to _copy_ the binutils package to various new
$ARCH-binutils packages. But hopefully the the infrastructure folks can
come up with some trick in package CVS or in koji which will make it
simpler than that.
