If netfilter changes the packet mark, the packet is rerouted. The
ip_route_me_harder family of functions fails to use the right sk, opting
to instead use skb->sk, resulting in a routing loop when used with
tunnels. Fixing this inside of the compat layer with skb_orphan would
work but would cause other problems, by disabling TSQ, so instead we
warn if the calling kernel hasn't yet backported the fix for this.

RHEL needs to apply https://lore.kernel.org/patchwork/patch/974664/

This kind of thing really makes me queezy and upset, but there's little
that can be done about such situations when dealing with Canonical's
kernel.

Kernels without 9feeb638cde0 ("tools build: fix # escaping in .cmd
files for future Make") face problems when building with more recent
make, so patch these to avoid issues.

gcc-10 switched to defaulting to -fno-common, which broke iproute2-5.4.
This was fixed in iproute-5.6, so switch to that. Because we're after a
stable testing surface, we generally don't like to bump these
unnecessarily, but in this case, being able to actually build is a basic
necessity.

While at some point it might have made sense to be running these tests
on ppc64 with 4k stacks, the kernel hasn't actually used 4k stacks on
64-bit powerpc in a long time, and more interesting things that we test
don't really work when we deviate from the default (16k). So, we stop
pushing our luck in this commit, and return to the default instead of
the minimum.

Before the 256 was just a guess, which was made wrong by qemu 5.0, so
instead actually query whether or not we're all set.

Coarse ktime is broken until [1] in 5.2 and kernels without the
backport, so we use fallback code there.
The fallback code has also been improved significantly. It now only uses
slower clocks on kernels < 3.17, at the expense of some accuracy we're
not overly concerned about.

This uses ELFv2 ABI, which is the only ppc64 ABI musl supports. Big
endian uses ELFv1 ABI, which musl doesn't support.

We can't do SMP this way, and we also fall back to using the default N32
ABI, which is a bummer. But the mips64r6 toolchain is too much of a
hassle to build with Gentoo's crossdev, and at least this works.
