Support all possible binary file formats in binutils

I needed to disassemble a binary today whose file format support isn’t currently compiled into homebrew’s `binutils`.

Rather than submitting another pull request to turn on just that format as in cf89b92c, d1ca8de6, and fed412f8, how about building all formats by default so that all the binutils can handle every binary file format in the world, out-of-the-box?

There’s also a minor patch to get it to build on clang.
