Clang: Find version-suffixed LLVM/Clang binutils

Debian renames all LLVM/Clang binaries with a version suffix to allow
multiple versions to be installed at the same time.  While there is a
version-agnostic package that adds a symlink to provide the standard
binary names, if only the versioned packages are installed, binaries
must be found as `binary-x.y`.  In any case, using the same version of
the `binutils` as the compiler seems better.
