Sparc64 doesn't care about you, and you shouldn't care about Sparc64

I 100% agree with you on this. If we can update binutils to the
latest and greatest, I believe powerpc64 would be able to work with
clang. I've backported several patches, with IBM's permission, to
binutils for handling new relocations, etc. However, not all patches
are straight forward, and currently we're missing something, which is
causing odd segfaults in ld(1), when linking as(1). No other binary,
only as(1). I've tried looking through it, but the binutils code is a
mess. I'm sure the bug that's getting hit was fixed with newer
binutils, but have had a very hard time trying to test with it.
TL;DR, let's update binutils at the very least, and gcc if it makes
sense. We shouldn't be relying on external toolchain for some archs,
and internal for others. It completely snubs already second class
citizens. Just look at the various build failures we've had because
to some people All The World is clang/x86.
