Yeah.  One build failure in three years does not sound to me like
something to panic about.  It sounds more like a local problem.
Also, I note that alligator is self-described as running a
"gcc experimental (nightly build)" compiler, so temporary build
glitches on it are hardly unexpected.

It seems like there's an increasing number of buildfarm animals whose
aims are less "test Postgres" than "test platform X by building
Postgres on it".  alligator is not the only experimental-tool-chain
animal, and fruitcrow (GNU Hurd) is another example we've been seeing
failures from lately.  I don't want to tell those folk to go away,
but maybe we should have some kind of annotation about "platform not
believed stable" to remind us not to put huge amounts of effort into
transient failures on those animals.
