We're still here.  Adélie.  The distro that does big endian and ELFv2.
The distro that *cares* about *quality*, not just hack-and-slashing.

We can't use Golang because Golang doesn't work on half of our
architectures - ppc32 will likely never be supported, and their ppc64
support is unusable and written very poorly.  It assumes POWER8, not to
mention the fact it likely has plenty of broken ELF ABI assumptions.
(There's also very poor support for other architectures with musl, but I
don't recall the specifics now.)

I'm sure you're aware of all of this already.  In fact, it was probably
your team that convinced Google that POWER7 is "old" when it is newer
than Sandy Bridge:

But I'm not sure if you work directly with Lynn or not, so I can't say
that for certain.

Anyway, GCC Go is definitely the best way forward for Adélie, which is
why we're trying to make it work on ppc64.  It already works perfectly
well on ppc32, x86*, and arm64.  And because it uses GCC's code
generator, it won't be subject to ridiculously unportable ABI assumptions.
