Previously, the conflict happened on the /usr/sbin/sendmail
file, and apk partially succeeded, leaving the filesystem in
an uncomfortable state. Now we detect the conflict as early
as possible.

Reported upstream by SuSE maintainer, though the way this works does
sort of bother me since this sort of code really shouldn't depend on
precision if written properly..

Fixes: #954

the file:

    sys/unix/syscall_linux_arm.go

seems to declare 'seek()' as a prototype, the implementation being:

    sys/unix/syscall_linux_gccgo_arm.go

however it isn't immediately clear why the conflict occurs, unless
it has to do with our Makefile patches, which CGO_ENABLED=1?

fixes #956

We add more functions to the unwind string comparisons, and pull in the
symbols for libucontext.

This patch reverts Node MR 43714[1], which broke time64 on pmmx.

Fixes: #935

Note that the checksums remain the same.

Also removes a hard-coded version number.

Commit e8adedc8 did not restore
the original -j1 as in be1bb024.

Unfortunately V8 does not support ppc and seemingly has no interest in
adopting a port.  In the future we will look for alternative JS runtimes
for running workloads on ppc.

We may also be able to package Node 12 since it has ppc support, with
the caveat that it is not well-supported upstream and will stop
receiving security updates.  This is still useful for some workloads
(Firefox builds, internal Homebridge, and such), perhaps.

Closes: #837

These are no longer required in the system/ repository.

The tools need libraries that should not be pulled into system/.
Additionally, since c-ares needs CMake now, it causes a dep cycle.

Fixes: #936

Note: checksums remain the same.

Appears to affect IPv6 only, which is causing automation
failures because 'abuild fetch' isn't falling back to
IPv4 in the event of an IPv6 failure.

I asked Daniel to remove the AAAA record if it won't be
repaired soon, but I'm not sure if/when he'll do that.

Estimated penalty, based on N=2 samples:

  * -j8: ~0-2 minutes
  * -j1: ~4-9 minutes

libucontext doesn't clear the stack frame below makecontext.  This
caused us to end up crashing like Solaris[1].

This workaround is already needed upstream for FreeBSD.  Let's go ahead
and use the same workaround for musl.  We also ensure they are not
declared `inline` so that they are available as library functions.

We also have a hack in place for the stage1 Ada driver due to their own
hack pulling in the Arm unwind functions directly without linking.

Fixes: #866 (and probably more as we continue building packages)
