[v3,3/3] toolchain/external: Codescape toolchains also exist for x86_64

From: Yann E. MORIN <yann.morin.1998@free.fr>

Since their prefix exactly matches our $(HOSTARCH), just use that.

Vicente, All,

Unfortunately, we currently can not do that, since we have a problem on
how we set and interpret $(HOSTARCH).

The problem is the same as that of the following build failures for the
Linaro toolchains:
    http://autobuild.buildroot.org/results/888/8889aa7d9fb48370e4760a6edbc6d3ae945f02f2/build-end.log

    >>> toolchain-external undefined Configurinannot execute
    >>> cross-compiler
    >>> '/home/test/autobuild/instance-1/output/host/opt/ext-toolchain/bin/arm-linux-gnueabihf-gcc'

The problem is that we set $(HOSTACH) with the output of `uname -m`,
which gives us the bitness (32 or 64) of the running kernel.

However, it is perfectly valid to run a 32-bit userland with a 64-bit
kernel. This can be the case if one is running a 32-bit chroot, like our
autobuilders do, for example.

So, until we fix that issue, I've marked this patch as Deferred in
Pathwork.

Regards,
Yann E. MORIN.
