Hmmm. My animals compile out of the source tree, not sure how this could
happen.

Indeed, no ccache. The compilers change often (well, once a week), I do
not want anything kept across compiler versions. The animals are really
testing the compilers as much as they are testing postgres.
However, there is an autoconf cache, but I do not see why it would have
such an effect.
So no clue.
