<pre>LLVM triple normalization seems to be mishandling "unknown" and empty
components; for example given "x86_64-unknown-linux-gnu" and "x86_64-linux-gnu"
which should be equivalent, triple normalization returns
"x86_64-unknown-linux-gnu" and "x86_64--linux-gnu".
autoconf's config.sub return "x86_64-unknown-linux-gnu" for both `config.sub
x86_64-linux-gnu` and `x86_64-unknown-linux-gnu`, LLVM triple normalization
should ideally behave the same way.</pre>
