Well, the question that's bothering me is how come "make check" in
an external build doesn't try to execute the temp-install rule before
printing that error message. Experimentation shows that it doesn't,
but it sure looks to me like it should: there's nothing conditional
about the "check: temp-install" dependency in Makefile.global. And
none of the three if-guards in the temp-install rule itself should
prevent this, so what is preventing it? I don't see it.

For this reason, I thought that adding NO_TEMP_INSTALL would be a good
safety factor in case somebody changes/breaks whatever unobvious
thing is keeping this from failing, and so I went ahead and did it.
