Ryan Burns 72b3badb61 lib.systems: add powerpc64-linux
PPC64 supports two ABIs: ELF v1 and v2.

ELFv1 is historically what GCC and most packages expect, but this is
changing because musl outright does not work with ELFv1. So any distro
which uses musl must use ELFv2. Many other platforms are moving to ELFv2
too, such as FreeBSD (as of v13) and Gentoo (as of late 2020).

Since we use musl extensively, let's default to ELFv2.

Nix gives us the power to specify this declaratively for the entire
system, so ELFv1 is not dropped entirely. It can be specified explicitly
in the target config, e.g. "powerpc64-unknown-linux-elfv1". Otherwise the
default is "powerpc64-unknown-linux-elfv2". For musl,
"powerpc64-unknown-linux-musl" must use elfv2 internally to function.

# We assert that the new algorithmic way of generating these lists matches the
# way they were hard-coded before.
#
# One might think "if we exhaustively test, what's the point of procedurally
# calculating the lists anyway?". The answer is one can mindlessly update these
# tests as new platforms become supported, and then just give the diff a quick
# sanity check before committing :).
