I disagree. Working with multiple target triplets is a fine thing, but
not inventing triplets you don't need is another. The idea that the

powerpc-linux is a good case in point of having too many triplets, with
variants such as powerpc64-*-linux*, powerpc-*-linux*spe*,
powerpc-*-linux*paired*, powerpc*-*-linux*altivec* that should just be
variants on the default options and multilibs for one target triplet.

Why is "more targets bad"? Life seems simple if you have one set of libraries for each target triple, so you have a "many target triples to one set of libraries" mapping. This implies that the major ABI differences get different triples though.
