Subject: [PATCH] requireFile: exit with non-zero error message
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since the script running is a failure condition, we should fail the
build properly, not leaving it up to the missing output to determine
that the build went wrong.  This should partly address #38952 — nix
build will print out the build log on non-zero exits.
