Remove CloudABI Binutils tools.

[ed]

Summary

As of FreeBSD 11, the cloudabi-toolchain port uses the ELF-toolchain
utilities for all the stuff not provided by LLVM. For FreeBSD 10 and
lower, we still rely on Binutils.

As CloudABI itself is only supported as of FreeBSD 11, there is hardly
any interest in supporting a Binutils based toolchain. Let's kick out
the CloudABI Binutils ports and symlink to the utilities in the base
system unconditionally.

Sounds good to me.

You should probably add this before the RUN_DEPENDS line:

IGNORE_FreeBSD_10= only for 11+

Well, that would be a bit too aggressive. Most of the tools set up by this port (e.g., Clang) work perfectly fine on 10.x. It's just that some tools on 11.x work better (e.g., readelf).

That is my impression too.
