Tom Lane 8efefa7487 Increase minimum supported GNU make version to 3.81. ... We've long held the minimum at 3.80, but that's required more than one workaround. Commit 0f39b70a6 broke it again, because it turns out that exporting a target-specific variable didn't work in 3.80. Considering that 3.81 is now old enough to get a driver's license, and that the only remaining buildfarm member testing 3.80 (prairiedog) is likely to be retired soon, let's just stop supporting 3.80. Adjust docs and Makefile.global's minimum-version check to match. There are a couple of comments in the Makefiles suggesting that random things could be done differently after we desupport 3.80, but I couldn't get excited about changing any of them right now. Back-patch to v15, as 0f39b70a6 was. Discussion: https://postgr.es/m/20220720172321.GL12702@telsasoft.com		2022-07-23 12:12:42 -04:00
